The same USB stick has been working fine on T420.

What's T420/T430? We shouldn't have to do research to answer your

Lenova laptops favored by some Linux users.
Do other Live Distros on other USB Flash Drives work on the T430?

I believe they are the type numbers of Thinkpad laptops. But then
again, I could be wrong. :)

You should find something here. Recipe rich, and too-long thread.

It's possible in your case, that some identifier is confused, and
it's not just booting from the USB stick.

What identifier?
Same HDD, same Ubuntu Live USB stick moved to newly acquired T430.
The only thing I can think of is BIOS. Or, USB bus is bad?

Yes, you're right about T420/T430 being ThinkPad model #. It's a new
T430 and I've only tried U18.04 & U20.04 USB Live. Both failed.
Could it be a BIOS setting ? UEFI ?

Oh, my.
It's a puzzle. I've not seen this pattern before. This exact pattern.
Instinct tells me, a user recently attempted to use GParted
to do something to his USB. And this is why the partition numbering
is now "funky".
But what ? What was the user trying to do at the time ? The reason
I'm trying to figure that out, is to guesstimate the damage pattern.
Where did the damage go ? What did it do ?
I'm looking at that pattern, and trying to tell what is going on.
I suspect maybe the Live Media being used to take the snapshot,
may have mounted the casper-rw for its own self.
The other part of the picture that cries out for attention, is
the two partitions that are exactly 12.75 GiB. I don't think
one is holding the other. That would not work. It could be
a coincidence, but on computers, these patterns are a "smell".
I would hold off on running "Boot-Repair" on that, until you figure
out how those partitions got out-of-spatial-order. Gparted will
renumber partitions on you, and that will break Grub on one partition
part of the sequence. That's where some information is read from
the ESP and used to find the location of the next stage of grub.
It is probably, at this point, indexing into the wrong partition.
First we have to review the history, the time line, and see
whether meddling with it as it sits now, is a bad idea or not.
If you're bored, make a backup of the stick. Macrium could do that,
since being from Windows, it will not try and mount anything for fun.
It uses smart backup for partitions it knows (FAT32, NTFS, EXTn),
and it will use "dd" for the ones it does not know (like a Microsoft
Reserved 16MB is done with dd as there is no file system).
Partition Name FS Mount Point Label Size
Used Unused Flags
/dev/sdb5 primary ext4 /media/xerus/casper-rw casper-rw 12.75GiB
2.42GiB 10.33GiB
/dev/sdb1 primary ntfs /media/xerus/usbdata usbdata 12.75GiB
64.91MiB 12.69GiB msftdata
It would be more normal for the ESP (sdb3) to be laid down first as sdb1.
It's 300MB, a sign that Ubuntu did it, and not a Windows thing.
Windows would use a 100MB ESP, which pisses off other Debians.
The partition numbering appears "wrong by expectation", but what
do I know. These things apparently happen all the time, this
weird stuff. But our job is to tip it upright, without breaking it.
Give us a summary, of the history of the thing, and what you've
tried to do to it since install (like, with Gparted).

No backup needed. It's just a Live Ubuntu USB Drive With Persistent
Storage created from an .iso file using mkusb. See instructions here...
How to Create a Live Ubuntu USB Drive With Persistent Storage https://www.howtogeek.com/howto/14912/create-a-persistent-bootable-ubuntu-usb-flash-drive/
I thought the Live Ubuntu USB drive is suppose to be portable until I
ran into this problem.

Try:

both before, and after, the hardware cabling changes.
Look for differences (other than the obvious ones).

Yours does not.
This means, somehow, the process to enumerate hardware either
isn't running, or there is an elevation problem (not enough
permissions to read the USB config space).
If you can find a log, maybe there's something in there which
indicates why the devices are not getting read properly.

But at least we can say "it wasn't a power problem". I was thinking,
when I asked for this info, that there would be evidence of the
device "winking out'. And that's not the case. I had to run the same
command on my machine, just to see what mine would look like. You
can see it did get a little snotty about the fourth part of my BT
dongle, but, it did manage to use "0b05:17cb" for all four entries.
And good ole Google, I'm not getting a result for "lsusb missing VID PID".
The thing is, to get as far as your lsusb got, the endpoints to the
USB devices must have formed. Otherwise, the tree view would not
exist. This means, at the physical layer, all the devices connected.
But somewhere in the USB stack (or DBUS or something), there is
a disconnect preventing the USB config space from being read
and parsed. Parsing your scanner for example, would find some
sort of scanner class info.

Why? Seems like there's no rhyme or reason.
Try:
lsusb -tv
both before, and after, the hardware cabling changes.
Look for differences (other than the obvious ones).

There's nothing abnormal there, so far. In terms of behavior, like
something showing up when you expect it to show up.

Notice how mine has the numbers, like 8087:0024
Yours does not.
This means, somehow, the process to enumerate hardware either
isn't running, or there is an elevation problem (not enough
permissions to read the USB config space).
If you can find a log, maybe there's something in there which
indicates why the devices are not getting read properly.
Here's the first ~100 lines of /var/log/syslog (showing error)...
Comment 1 at the bottom here:
https://bugzilla.redhat.com/show_bug.cgi?id=1369161
"Dan mentioned the commit [1] there that removed the legacy support
for WEP cipher suites in group cipher announced in RSN IE"
The regulatory database for the Wifi appears to have got updated.
That affects how the Wifi module behaves in different countries,
to follow country specific rules. Even 2.4GHz Wifi, does not have
the same band plan and channel numbers, in the US and Europe.
So at least the dbus message does not mean that dbus failed.
As for the extended period of the supplicant messing about,
I don't take that as a hardware failure, or a failure to
communicate on the USB bus. I don't think the root cause of the
USB problem is in there.
It might have had something to do with what is in here.
But whatever is in cron.daily, could be kicking off a ton of
maintenance activity.

This means, somehow, the process to enumerate hardware either

If you can find a log, maybe there's something in there which

Libusb keeps the info that lsusb uses.
https://libusb.sourceforge.io/api-1.0/structlibusb__device__descriptor.html
https://github.com/libusb/libusb/blob/master/libusb/libusb.h
enum libusb_error {
LIBUSB_SUCCESS = 0, <=== This is the rc
= value thing below
https://github.com/gregkh/usbutils/blob/master/lsusb.c
3539 libusb_get_device_descriptor(dev, &desc); <=== The code
chucks away useful info...
And you can see people fooling around with it here. Notice how
they checked for a return code.
https://stackoverflow.com/questions/14722083/how-to-use-libusb-and-libusb-get-device-descriptor
rc = libusb_get_device_descriptor(device, &desc);
The lsusb does not check the return code, and throws it away.
Since this is userland stuff, you can:
1) Go to synaptic and edit the repostories and click the "source
repository".
2) Make sure build-essentials package is installed (has a compiler for example).
3) Follow a recipe for building code from source on Ubuntu.
4) You can then edit the source, change the code to look like this. Then recompile.
int rc;
rc = libusb_get_device_descriptor(device, &desc);
if (rc != 0) printf("got a RC of %d for
libusb_get_device_descriptor\n", rc);
Anyway, I know you're not going to do that, so that's... just an idea.
I'm sure that the logic of the lsusb.c does cleverly cover off this situation,
in an indirect way, but I would prefer to see the error printed immediately when there's a problem. There really isn't a very rich vocabulary for
the rc= errors in this case.
LIBUSB_SUCCESS = 0,
LIBUSB_ERROR_IO = -1,
LIBUSB_ERROR_INVALID_PARAM = -2,
LIBUSB_ERROR_ACCESS = -3,
LIBUSB_ERROR_NO_DEVICE = -4,
LIBUSB_ERROR_NOT_FOUND = -5,
LIBUSB_ERROR_BUSY = -6,
LIBUSB_ERROR_TIMEOUT = -7,
LIBUSB_ERROR_OVERFLOW = -8,
LIBUSB_ERROR_PIPE = -9,
/** System call interrupted (perhaps due to signal) */
LIBUSB_ERROR_INTERRUPTED = -10,
LIBUSB_ERROR_NO_MEM = -11,
LIBUSB_ERROR_NOT_SUPPORTED = -12,
LIBUSB_ERROR_OTHER = -99
*******
Summary: While you might thing I was stupid for going through that path,
the bread crumb from the above, gives me this. Try running
sudo lsusb -tv and see if the detail printed is better.
https://stackoverflow.com/questions/40597515/libusb-calls-without-sudo-using-udev-rules
Mow, looking at that discussion thread, does Ubuntu use udev ? And if so, would yours be subtly screwed up ?

"Dan mentioned the commit [1] there that removed the legacy support

The regulatory database for the Wifi appears to have got updated.
That affects how the Wifi module behaves in different countries,
to follow country specific rules. Even 2.4GHz Wifi, does not have
the same band plan and channel numbers, in the US and Europe.
So at least the dbus message does not mean that dbus failed.
As for the extended period of the supplicant messing about,
I don't take that as a hardware failure, or a failure to
communicate on the USB bus. I don't think the root cause of the
USB problem is in there.
Yes, the wifi error seems separate from the USB issue.
It might have had something to do with what is in here.
But whatever is in cron.daily, could be kicking off a ton of
maintenance activity.

Should something be removed?
OK, reproduced here (using a Linux Mint 19.1 stick in Live mode)
and the library call I was worried about was not the problem.
I added three debug statements to "lsusb" and none of them
triggered.
Instead, the message about /usr/share/usb.ids being missing is important. Maybe you saw that in your output.
cd /usr/share # where the file
should be
ls -al usb.ids # verify it is missing
ls -al /var/lib/usbutils/usb.ids # installed by the
.deb ???
sudo ln -s /var/lib/usbutils/usb.ids usb.ids # softlink it in so
code can find it
Now, lsusb -tv should properly list the hardware.
Test and see.

Why? Seems like there's no rhyme or reason.
Try:
lsusb -tv
both before, and after, the hardware cabling changes.
Look for differences (other than the obvious ones).

The regulatory database for the Wifi appears to have got updated.
That affects how the Wifi module behaves in different countries,
to follow country specific rules. Even 2.4GHz Wifi, does not have
the same band plan and channel numbers, in the US and Europe.
So at least the dbus message does not mean that dbus failed.
As for the extended period of the supplicant messing about,
I don't take that as a hardware failure, or a failure to
communicate on the USB bus. I don't think the root cause of the
USB problem is in there.
Yes, the wifi error seems separate from the USB issue.
It might have had something to do with what is in here.
But whatever is in cron.daily, could be kicking off a ton of
maintenance activity.

Should something be removed?
OK, reproduced here (using a Linux Mint 19.1 stick in Live mode)
and the library call I was worried about was not the problem.
I added three debug statements to "lsusb" and none of them
triggered.
Instead, the message about /usr/share/usb.ids being missing is
important.
Maybe you saw that in your output.
cd /usr/share # where the file
should be
ls -al usb.ids # verify it is missing >>> ls -al /var/lib/usbutils/usb.ids # installed by the
.deb ???
sudo ln -s /var/lib/usbutils/usb.ids usb.ids # softlink it in so
code can find it
Now, lsusb -tv should properly list the hardware.
Test and see.

Scan failed still (with and without the link to
/var/lib/usbutils/usb.ids)...
https://i.postimg.cc/MGbzMPHB/Simple-Scan-Failed-to-scan-Error-communicating-with-scanner.png
I've been having this scan issue since FOREVER. Scan does NOT scan
consistently.
Weird.
Well then, you might need to add the three changes to the code and
print out the return code from the call then. My failure highlighted the packaging issue, rather than reproduce your scanning problem.
I picked up the original one here, to use for modification.
https://launchpad.net/ubuntu/+source/usbutils/1:007-4
usbutils_007.orig.tar.xz 408.5 KiB 7593a01724bbc0fd9fe48e62bc721ceb61c76654f1d7b231b3c65f6dfbbaefa4
I picked that one, since I was using Linux Mint, and it does not have
a "source" repository. And so I searched around and found a version
which matched my USB stick version.
Then opened lsusb.c and modified the code.
ret = libusb_open(dev, &udev);
if (ret) {
fprintf(stderr, "Couldn't open device, some information "
"will be missing\n");
udev = NULL;
}
libusb_get_device_descriptor(dev, &desc);
Changed to look like this. Needs an "int ret" of some kind, to
hold the return code from the routine.
ret = libusb_open(dev, &udev);
if (ret) {
fprintf(stderr, "Couldn't open device, some information "
"will be missing\n");
udev = NULL;
}
ret = libusb_get_device_descriptor(dev, &desc);
if (ret) {
fprintf(stderr, "libusb_get_device_descriptor returned %d at
line 3813\n", ret);
}
That needs to be done in a total of three places, and salt the line
number fixed value,
with the value your text editor displays for that fprintf statement. The
line number
is so you know which one triggered.
That's just in case your particular failure, is something I'm not seeing here,
when I modified lsusb.c and rebuilt it.
cd unpacked_dir_with_source
nano lsusb.c # edit source
./configure # needs sudo apt install
build-essentials so you have a gcc present
# also needs libusb-dev added as well,
to get a libusb.h .
# sudo apt install libusb-dev
make # Should compile OK, assuming no typos
and you created a "int ret".
./lsusb -tv # Test your creation, see if it throws errors or not.
I tried systemctl --all status and the daemons all appeared to be
running and there was no suspicious stuff visible in mine.

Why? Seems like there's no rhyme or reason.
Try:
lsusb -tv
both before, and after, the hardware cabling changes.
Look for differences (other than the obvious ones).

Scan failed still (with and without the link to
/var/lib/usbutils/usb.ids)...
https://i.postimg.cc/MGbzMPHB/Simple-Scan-Failed-to-scan-Error-communicating-with-scanner.png
I've been having this scan issue since FOREVER. Scan does NOT scan
consistently.
Weird.
Well then, you might need to add the three changes to the code and
print out the return code from the call then. My failure highlighted the >>> packaging issue, rather than reproduce your scanning problem.
I picked up the original one here, to use for modification.
https://launchpad.net/ubuntu/+source/usbutils/1:007-4
usbutils_007.orig.tar.xz 408.5 KiB
7593a01724bbc0fd9fe48e62bc721ceb61c76654f1d7b231b3c65f6dfbbaefa4
I picked that one, since I was using Linux Mint, and it does not have
a "source" repository. And so I searched around and found a version
which matched my USB stick version.
Then opened lsusb.c and modified the code.
ret = libusb_open(dev, &udev);
if (ret) {
fprintf(stderr, "Couldn't open device, some information "
"will be missing\n");
udev = NULL;
}
libusb_get_device_descriptor(dev, &desc);
Changed to look like this. Needs an "int ret" of some kind, to
hold the return code from the routine.
ret = libusb_open(dev, &udev);
if (ret) {
fprintf(stderr, "Couldn't open device, some information "
"will be missing\n");
udev = NULL;
}
ret = libusb_get_device_descriptor(dev, &desc);
if (ret) {
fprintf(stderr, "libusb_get_device_descriptor returned %d at
line 3813\n", ret);
}
That needs to be done in a total of three places, and salt the line
number fixed value,
with the value your text editor displays for that fprintf statement. The >>> line number
is so you know which one triggered.
That's just in case your particular failure, is something I'm not seeing >>> here,
when I modified lsusb.c and rebuilt it.
cd unpacked_dir_with_source
nano lsusb.c # edit source
./configure # needs sudo apt install
build-essentials so you have a gcc present
# also needs libusb-dev added as well, >>> to get a libusb.h .
# sudo apt install libusb-dev
make # Should compile OK, assuming no typos >>> and you created a "int ret".
./lsusb -tv # Test your creation, see if it throws >>> errors or not.
I tried systemctl --all status and the daemons all appeared to be
running and there was no suspicious stuff visible in mine.

Any way to convert HP ScanJet 6300C into a network scanner rather than

Why? Seems like there's no rhyme or reason.
Try:
lsusb -tv
both before, and after, the hardware cabling changes.
Look for differences (other than the obvious ones).

Notice how mine has the numbers, like 8087:0024
Yours does not.
This means, somehow, the process to enumerate hardware either
isn't running, or there is an elevation problem (not enough
permissions to read the USB config space).
If you can find a log, maybe there's something in there which
indicates why the devices are not getting read properly.
Here's the first ~100 lines of /var/log/syslog (showing error)... >>>>>>>

Comment 1 at the bottom here:
https://bugzilla.redhat.com/show_bug.cgi?id=1369161
"Dan mentioned the commit [1] there that removed the legacy
support
for WEP cipher suites in group cipher announced in RSN IE"
The regulatory database for the Wifi appears to have got updated.
That affects how the Wifi module behaves in different countries,
to follow country specific rules. Even 2.4GHz Wifi, does not have
the same band plan and channel numbers, in the US and Europe.
So at least the dbus message does not mean that dbus failed.
As for the extended period of the supplicant messing about,
I don't take that as a hardware failure, or a failure to
communicate on the USB bus. I don't think the root cause of the
USB problem is in there.
Yes, the wifi error seems separate from the USB issue.
It might have had something to do with what is in here.
But whatever is in cron.daily, could be kicking off a ton of
maintenance activity.

I've been having this scan issue since FOREVER. Scan does NOT scan
consistently.
Weird.
Well then, you might need to add the three changes to the code and
print out the return code from the call then. My failure highlighted the
packaging issue, rather than reproduce your scanning problem.
I picked up the original one here, to use for modification.

I picked that one, since I was using Linux Mint, and it does not have
a "source" repository. And so I searched around and found a version
which matched my USB stick version.
Then opened lsusb.c and modified the code.
ret = libusb_open(dev, &udev);
if (ret) {
fprintf(stderr, "Couldn't open device, some information "
"will be missing\n");
udev = NULL;
}
libusb_get_device_descriptor(dev, &desc);
Changed to look like this. Needs an "int ret" of some kind, to
hold the return code from the routine.
ret = libusb_open(dev, &udev);
if (ret) {
fprintf(stderr, "Couldn't open device, some information "
"will be missing\n");
udev = NULL;
}
ret = libusb_get_device_descriptor(dev, &desc);
if (ret) {
fprintf(stderr, "libusb_get_device_descriptor returned %d at
line 3813\n", ret);
}
That needs to be done in a total of three places, and salt the line
number fixed value,
with the value your text editor displays for that fprintf statement. The
line number
is so you know which one triggered.
That's just in case your particular failure, is something I'm not seeing
here,
when I modified lsusb.c and rebuilt it.
cd unpacked_dir_with_source
nano lsusb.c # edit source
./configure # needs sudo apt install
build-essentials so you have a gcc present
# also needs libusb-dev added as well,
to get a libusb.h .
# sudo apt install libusb-dev
make # Should compile OK, assuming no typos
and you created a "int ret".
./lsusb -tv # Test your creation, see if it throws
errors or not.
I tried systemctl --all status and the daemons all appeared to be
running and there was no suspicious stuff visible in mine.

Why? Seems like there's no rhyme or reason.
Try:
lsusb -tv
both before, and after, the hardware cabling changes.
Look for differences (other than the obvious ones).

So at least the dbus message does not mean that dbus failed.
As for the extended period of the supplicant messing about,
I don't take that as a hardware failure, or a failure to
communicate on the USB bus. I don't think the root cause of the
USB problem is in there.
Yes, the wifi error seems separate from the USB issue.
It might have had something to do with what is in here.
But whatever is in cron.daily, could be kicking off a ton of
maintenance activity.

Should something be removed?
OK, reproduced here (using a Linux Mint 19.1 stick in Live mode)
and the library call I was worried about was not the problem.
I added three debug statements to "lsusb" and none of them
triggered.
Instead, the message about /usr/share/usb.ids being missing is
important.
Maybe you saw that in your output.
cd /usr/share # where the file
should be
ls -al usb.ids # verify it is
missing
ls -al /var/lib/usbutils/usb.ids # installed by the
.deb ???
sudo ln -s /var/lib/usbutils/usb.ids usb.ids # softlink it in so >>>>> code can find it
Now, lsusb -tv should properly list the hardware.
Test and see.

So at least the dbus message does not mean that dbus failed.

Yes, the wifi error seems separate from the USB issue.
It might have had something to do with what is in here.

Should something be removed?
OK, reproduced here (using a Linux Mint 19.1 stick in Live mode)
and the library call I was worried about was not the problem.
I added three debug statements to "lsusb" and none of them
triggered.
Instead, the message about /usr/share/usb.ids being missing is
important.
Maybe you saw that in your output.
cd /usr/share # where the file >>>>>> should be
ls -al usb.ids # verify it is
missing
ls -al /var/lib/usbutils/usb.ids # installed by the >>>>>> .deb ???
sudo ln -s /var/lib/usbutils/usb.ids usb.ids # softlink it in so >>>>>> code can find it
Now, lsusb -tv should properly list the hardware.
Test and see.

Scan failed still (with and without the link to
/var/lib/usbutils/usb.ids)...
https://i.postimg.cc/MGbzMPHB/Simple-Scan-Failed-to-scan-Error-communicating-with-scanner.png
I've been having this scan issue since FOREVER. Scan does NOT scan
consistently.
Weird.
Well then, you might need to add the three changes to the code and
print out the return code from the call then. My failure highlighted
the
packaging issue, rather than reproduce your scanning problem.
I picked up the original one here, to use for modification.
https://launchpad.net/ubuntu/+source/usbutils/1:007-4
usbutils_007.orig.tar.xz 408.5 KiB
7593a01724bbc0fd9fe48e62bc721ceb61c76654f1d7b231b3c65f6dfbbaefa4
I picked that one, since I was using Linux Mint, and it does not have
a "source" repository. And so I searched around and found a version
which matched my USB stick version.
Then opened lsusb.c and modified the code.
ret = libusb_open(dev, &udev);
if (ret) {
fprintf(stderr, "Couldn't open device, some information "
"will be missing\n");
udev = NULL;
}
libusb_get_device_descriptor(dev, &desc);
Changed to look like this. Needs an "int ret" of some kind, to
hold the return code from the routine.
ret = libusb_open(dev, &udev);
if (ret) {
fprintf(stderr, "Couldn't open device, some information "
"will be missing\n");
udev = NULL;
}
ret = libusb_get_device_descriptor(dev, &desc);
if (ret) {
fprintf(stderr, "libusb_get_device_descriptor returned %d at
line 3813\n", ret);
}
That needs to be done in a total of three places, and salt the line
number fixed value,
with the value your text editor displays for that fprintf statement.
The
line number
is so you know which one triggered.
That's just in case your particular failure, is something I'm not
seeing
here,
when I modified lsusb.c and rebuilt it.
cd unpacked_dir_with_source
nano lsusb.c # edit source
./configure # needs sudo apt install
build-essentials so you have a gcc present
# also needs libusb-dev added as
well,
to get a libusb.h .
# sudo apt install libusb-dev
make # Should compile OK, assuming no
typos
and you created a "int ret".
./lsusb -tv # Test your creation, see if it
throws
errors or not.
I tried systemctl --all status and the daemons all appeared to be
running and there was no suspicious stuff visible in mine.

Any way to convert HP ScanJet 6300C into a network scanner rather than
using USB connection ?
Okay, found something on Network Scanning...
https://help.ubuntu.com/community/Scanners
The 6300c spec was written in the year 1999, using Acrobat 3.01
to make the PDF :-)
USB and SCSI compatible
That means the thing is USB 1.1 , at a guess. My year 2000 machine
didn't have USB2. It might have been 2005, when the BIOS screens
got a page for USB2 configuration.
And this isn't really all bad, since scanners of that era, only
produced scan data at 1MB/sec or 2MB/sec or so. USB 1.1 might
manage 1MB/sec (instead of the wire-rate 1.5MB/sec).
My scanner is a SCSI, and I use an Adaptec 2906 to drive it. The
interface is Async SCSI, and the transfer rate improves, the
shorter the cable is. The electrical time of flight, matters
a bit for async SCSI. Both your and my scanner, are not fast
enough for this detail on the cable, to matter. I could use
a longer cable, without insult to the thing.
To answer your question then, the odds of a network cable sprouting
out the side of that unit, are zero. I don't see a mention of
any plugin card, with network connector on it.
The advertising material touts the transfer time... when the unit
is scanning in monochrome mode. It is to laugh. There isn't really
an admission of how slow it gets, when used the way a user would
want to use it (flat out, full color).
Mine takes 2 minutes, to do a scan at highest possible resolution
and in 36 bit color. And that's with the SCSI interface (so the
interface is not the limiting issue). Xsane does not run my scanner
properly, so I can't use Linux for it. It has run since I got it,
under MacOSX.
The USB though, should be compatible enough, to work with that
thing. Even a USB3 port on my current machine, should work
with your USB1.1 scanner. No excuses there.
And the scanner is powered from mains power, so we cannot blame
a USB fuse blowing as an excuse for non-operation.
Paul
Just found the packing slip (dated June 28, 2000) from the box. :-)
UPC: 0088698899052
https://i.postimg.cc/MGbzMPHB/Simple-Scan-Failed-to-scan-Error-communicating-with-scanner.png
Why does it scan sometimes and not others ? Like playing lottery.
Does it need a driver for the scanner ? hplip, right ?
Or, are older scanners no longer supported ?
That's discrimination against seniors. :-(

Should something be removed?
OK, reproduced here (using a Linux Mint 19.1 stick in Live mode) >>>>>>> and the library call I was worried about was not the problem.
I added three debug statements to "lsusb" and none of them
triggered.
Instead, the message about /usr/share/usb.ids being missing is
important.
Maybe you saw that in your output.
cd /usr/share # where the file
should be
ls -al usb.ids # verify it is
missing
ls -al /var/lib/usbutils/usb.ids # installed by the
.deb ???
sudo ln -s /var/lib/usbutils/usb.ids usb.ids # softlink it in so
code can find it
Now, lsusb -tv should properly list the hardware.
Test and see.

I've been having this scan issue since FOREVER. Scan does NOT scan >>>>>> consistently.
Weird.
Well then, you might need to add the three changes to the code and
print out the return code from the call then. My failure highlighted >>>>> the
packaging issue, rather than reproduce your scanning problem.
I picked up the original one here, to use for modification.
https://launchpad.net/ubuntu/+source/usbutils/1:007-4
usbutils_007.orig.tar.xz 408.5 KiB
7593a01724bbc0fd9fe48e62bc721ceb61c76654f1d7b231b3c65f6dfbbaefa4
I picked that one, since I was using Linux Mint, and it does not have >>>>> a "source" repository. And so I searched around and found a version
which matched my USB stick version.
Then opened lsusb.c and modified the code.
ret = libusb_open(dev, &udev);
if (ret) {
fprintf(stderr, "Couldn't open device, some information "
"will be missing\n");
udev = NULL;
}
libusb_get_device_descriptor(dev, &desc);
Changed to look like this. Needs an "int ret" of some kind, to
hold the return code from the routine.
ret = libusb_open(dev, &udev);
if (ret) {
fprintf(stderr, "Couldn't open device, some information "
"will be missing\n");
udev = NULL;
}
ret = libusb_get_device_descriptor(dev, &desc);
if (ret) {
fprintf(stderr, "libusb_get_device_descriptor returned %d at
line 3813\n", ret);
}
That needs to be done in a total of three places, and salt the line
number fixed value,
with the value your text editor displays for that fprintf statement. >>>>> The
line number
is so you know which one triggered.
That's just in case your particular failure, is something I'm not
seeing
here,
when I modified lsusb.c and rebuilt it.
cd unpacked_dir_with_source
nano lsusb.c # edit source
./configure # needs sudo apt install
build-essentials so you have a gcc present
# also needs libusb-dev added as
well,
to get a libusb.h .
# sudo apt install libusb-dev
make # Should compile OK, assuming no
typos
and you created a "int ret".
./lsusb -tv # Test your creation, see if it
throws
errors or not.
I tried systemctl --all status and the daemons all appeared to be
running and there was no suspicious stuff visible in mine.

Any way to convert HP ScanJet 6300C into a network scanner rather than >>>> using USB connection ?
Okay, found something on Network Scanning...
https://help.ubuntu.com/community/Scanners
The 6300c spec was written in the year 1999, using Acrobat 3.01
to make the PDF :-)
USB and SCSI compatible
That means the thing is USB 1.1 , at a guess. My year 2000 machine
didn't have USB2. It might have been 2005, when the BIOS screens
got a page for USB2 configuration.
And this isn't really all bad, since scanners of that era, only
produced scan data at 1MB/sec or 2MB/sec or so. USB 1.1 might
manage 1MB/sec (instead of the wire-rate 1.5MB/sec).
My scanner is a SCSI, and I use an Adaptec 2906 to drive it. The
interface is Async SCSI, and the transfer rate improves, the
shorter the cable is. The electrical time of flight, matters
a bit for async SCSI. Both your and my scanner, are not fast
enough for this detail on the cable, to matter. I could use
a longer cable, without insult to the thing.
To answer your question then, the odds of a network cable sprouting
out the side of that unit, are zero. I don't see a mention of
any plugin card, with network connector on it.
The advertising material touts the transfer time... when the unit
is scanning in monochrome mode. It is to laugh. There isn't really
an admission of how slow it gets, when used the way a user would
want to use it (flat out, full color).
Mine takes 2 minutes, to do a scan at highest possible resolution
and in 36 bit color. And that's with the SCSI interface (so the
interface is not the limiting issue). Xsane does not run my scanner
properly, so I can't use Linux for it. It has run since I got it,
under MacOSX.
The USB though, should be compatible enough, to work with that
thing. Even a USB3 port on my current machine, should work
with your USB1.1 scanner. No excuses there.
And the scanner is powered from mains power, so we cannot blame
a USB fuse blowing as an excuse for non-operation.
Paul

Oh, the possibilities. :-)

Any way to convert HP ScanJet 6300C into a network scanner rather than >>>>> using USB connection ?
Okay, found something on Network Scanning...
https://help.ubuntu.com/community/Scanners
The 6300c spec was written in the year 1999, using Acrobat 3.01
to make the PDF :-)
USB and SCSI compatible
That means the thing is USB 1.1 , at a guess. My year 2000 machine
didn't have USB2. It might have been 2005, when the BIOS screens
got a page for USB2 configuration.
And this isn't really all bad, since scanners of that era, only
produced scan data at 1MB/sec or 2MB/sec or so. USB 1.1 might
manage 1MB/sec (instead of the wire-rate 1.5MB/sec).
My scanner is a SCSI, and I use an Adaptec 2906 to drive it. The
interface is Async SCSI, and the transfer rate improves, the
shorter the cable is. The electrical time of flight, matters
a bit for async SCSI. Both your and my scanner, are not fast
enough for this detail on the cable, to matter. I could use
a longer cable, without insult to the thing.
To answer your question then, the odds of a network cable sprouting
out the side of that unit, are zero. I don't see a mention of
any plugin card, with network connector on it.
The advertising material touts the transfer time... when the unit
is scanning in monochrome mode. It is to laugh. There isn't really
an admission of how slow it gets, when used the way a user would
want to use it (flat out, full color).
Mine takes 2 minutes, to do a scan at highest possible resolution
and in 36 bit color. And that's with the SCSI interface (so the
interface is not the limiting issue). Xsane does not run my scanner
properly, so I can't use Linux for it. It has run since I got it,
under MacOSX.
The USB though, should be compatible enough, to work with that
thing. Even a USB3 port on my current machine, should work
with your USB1.1 scanner. No excuses there.
And the scanner is powered from mains power, so we cannot blame
a USB fuse blowing as an excuse for non-operation.
Paul
https://help.ubuntu.com/community/ScanningHowTo
[see Sharing a Scanner Over a Network - 1) The scanner is connected a
computer - the server - and shared over the network.]
Raspberry Pi server ? Scanner ? VOIP ?
Oh, the possibilities. :-)
What I'd like to see, is your udev working properly when a USB
item is hotplugged. There is a logging system, and a way to turn
on or adjust logging for udev. Keywords udevadm and journalxe or so.
I'm just surprised it's so hard to get answers from the machine.
I really used to like looking in "dmesg" and seeing a breadcrumb
waiting for me. dmesg is not what it used to be. It's been
tampered with. I've even had cases recently, where dmesg would
not run. Years ago, it always worked.
As for the scanner types, I'm surprised someone has not piped
up and suggested replacing the scanner. I'm not even sure a
discrete scanner would be in my computer store today, and it
might be part of an inkjet printer.
The old scanners used CCD. It has depth of field. If you lay
a bound book on the scanner, it tends to photograph "some"
of the words as they curve at the binding. Modern scanners
are mostly CMOS, the focus is sharp, the depth of field is
poor. If you lay a bound book on the surface, a modern scanner
records words near the binder as a grey blur. That's the
difference.
For sheet fed stock, the CMOS is fine, because you can press
the sheet firmly against the glass. But any time the target
won't stay on the glass, there's a possibility the CMOS
won't register the item well.
I would prefer your USB to be working, so any future USB items
will also work. In hardware, things always start with a PCI block,
the USB logic block would be under that, and the USB PHY then
connects to your device. It really should not be flaky. The PCI
driver handles either PCI or PCI Express. While it might say
PCI, the bridge could actually operate at 32GB/sec if necessary.
They design the hardware blocks, to "look like" PCI, so a bog
standard driver can do the work.
You can try "lspci" and see the mess that's in there, if you
want some idea of portions of the next layer up. and I'm referring
to bits of stuff inside the Southbridge, where at least some
of your USB ports live.

Why? Seems like there's no rhyme or reason.
Try:
lsusb -tv
both before, and after, the hardware cabling changes.
Look for differences (other than the obvious ones).

Yes, the wifi error seems separate from the USB issue.

Should something be removed?
OK, reproduced here (using a Linux Mint 19.1 stick in Live mode)
and the library call I was worried about was not the problem.
I added three debug statements to "lsusb" and none of them
triggered.
Instead, the message about /usr/share/usb.ids being missing is
important.
Maybe you saw that in your output.
cd /usr/share # where the file >>>>>> should be

Scan failed still (with and without the link to
/var/lib/usbutils/usb.ids)...
https://i.postimg.cc/MGbzMPHB/Simple-Scan-Failed-to-scan-Error-communicating-with-scanner.png
I've been having this scan issue since FOREVER. Scan does NOT scan
consistently.
Weird.
Well then, you might need to add the three changes to the code and
print out the return code from the call then. My failure highlighted
the
packaging issue, rather than reproduce your scanning problem.
I picked up the original one here, to use for modification.
https://launchpad.net/ubuntu/+source/usbutils/1:007-4
usbutils_007.orig.tar.xz 408.5 KiB
7593a01724bbc0fd9fe48e62bc721ceb61c76654f1d7b231b3c65f6dfbbaefa4
I picked that one, since I was using Linux Mint, and it does not have
a "source" repository. And so I searched around and found a version
which matched my USB stick version.
Then opened lsusb.c and modified the code.
ret = libusb_open(dev, &udev);
if (ret) {
fprintf(stderr, "Couldn't open device, some information "
"will be missing\n");
udev = NULL;
}
libusb_get_device_descriptor(dev, &desc);
Changed to look like this. Needs an "int ret" of some kind, to
hold the return code from the routine.
ret = libusb_open(dev, &udev);
if (ret) {
fprintf(stderr, "Couldn't open device, some information "
"will be missing\n");
udev = NULL;
}
ret = libusb_get_device_descriptor(dev, &desc);
if (ret) {
fprintf(stderr, "libusb_get_device_descriptor returned %d at
line 3813\n", ret);
}
That needs to be done in a total of three places, and salt the line
number fixed value,
with the value your text editor displays for that fprintf statement.
The
line number
is so you know which one triggered.
That's just in case your particular failure, is something I'm not
seeing
here,
when I modified lsusb.c and rebuilt it.
cd unpacked_dir_with_source
nano lsusb.c # edit source
./configure # needs sudo apt install
build-essentials so you have a gcc present
# also needs libusb-dev added as
well,
to get a libusb.h .
# sudo apt install libusb-dev
make # Should compile OK, assuming no
typos
and you created a "int ret".
./lsusb -tv # Test your creation, see if it
throws
errors or not.
I tried systemctl --all status and the daemons all appeared to be
running and there was no suspicious stuff visible in mine.

Any way to convert HP ScanJet 6300C into a network scanner rather than
using USB connection ?
Okay, found something on Network Scanning...
https://help.ubuntu.com/community/Scanners
The 6300C spec was written in the year 1999, using Acrobat 3.01
to make the PDF :-)
USB and SCSI compatible
That means the thing is USB 1.1 , at a guess. My year 2000 machine
didn't have USB2. It might have been 2005, when the BIOS screens
got a page for USB2 configuration.
And this isn't really all bad, since scanners of that era, only
produced scan data at 1MB/sec or 2MB/sec or so. USB 1.1 might
manage 1MB/sec (instead of the wire-rate 1.5MB/sec).
My scanner is a SCSI, and I use an Adaptec 2906 to drive it. The
interface is Async SCSI, and the transfer rate improves, the
shorter the cable is. The electrical time of flight, matters
a bit for async SCSI. Both your and my scanner, are not fast
enough for this detail on the cable, to matter. I could use
a longer cable, without insult to the thing.
To answer your question then, the odds of a network cable sprouting
out the side of that unit, are zero. I don't see a mention of
any plugin card, with network connector on it.
The advertising material touts the transfer time... when the unit
is scanning in monochrome mode. It is to laugh. There isn't really
an admission of how slow it gets, when used the way a user would
want to use it (flat out, full color).
Mine takes 2 minutes, to do a scan at highest possible resolution
and in 36 bit color. And that's with the SCSI interface (so the
interface is not the limiting issue). Xsane does not run my scanner
properly, so I can't use Linux for it. It has run since I got it,
under MacOSX.
The USB though, should be compatible enough, to work with that
thing. Even a USB3 port on my current machine, should work
with your USB1.1 scanner. No excuses there.
And the scanner is powered from mains power, so we cannot blame
a USB fuse blowing as an excuse for non-operation.

Why does it scan sometimes and not others ? Like playing lottery.
Does it need a driver for the scanner ? hplip, right ?
Or, are older scanners no longer supported ?
That's discrimination against seniors. :-(
Start Simple Scan from the command line, and see if it throws
any info out during the run attempt.
Oh, one other warning...
$ snap list
$ which simplescan # or whatever the executable for it happens to
be named
See if SimpleScan is a snap package :-/
Then you have the added "advantage" of debugging Canonicals
"booby trapped crapcicle".
It could be the reason it is failing, is because it is a Snap.

Mine shows it is not a Snap.
The command has a debug option.
simple-scan -d
that you can use from Terminal.

Any way to convert HP ScanJet 6300C into a network scanner rather
than
using USB connection ?
Okay, found something on Network Scanning...
https://help.ubuntu.com/community/Scanners
The 6300c spec was written in the year 1999, using Acrobat 3.01
to make the PDF :-)
USB and SCSI compatible
That means the thing is USB 1.1 , at a guess. My year 2000 machine
didn't have USB2. It might have been 2005, when the BIOS screens
got a page for USB2 configuration.
And this isn't really all bad, since scanners of that era, only
produced scan data at 1MB/sec or 2MB/sec or so. USB 1.1 might
manage 1MB/sec (instead of the wire-rate 1.5MB/sec).
My scanner is a SCSI, and I use an Adaptec 2906 to drive it. The
interface is Async SCSI, and the transfer rate improves, the
shorter the cable is. The electrical time of flight, matters
a bit for async SCSI. Both your and my scanner, are not fast
enough for this detail on the cable, to matter. I could use
a longer cable, without insult to the thing.
To answer your question then, the odds of a network cable sprouting
out the side of that unit, are zero. I don't see a mention of
any plugin card, with network connector on it.
The advertising material touts the transfer time... when the unit
is scanning in monochrome mode. It is to laugh. There isn't really
an admission of how slow it gets, when used the way a user would
want to use it (flat out, full color).
Mine takes 2 minutes, to do a scan at highest possible resolution
and in 36 bit color. And that's with the SCSI interface (so the
interface is not the limiting issue). Xsane does not run my scanner
properly, so I can't use Linux for it. It has run since I got it,
under MacOSX.
The USB though, should be compatible enough, to work with that
thing. Even a USB3 port on my current machine, should work
with your USB1.1 scanner. No excuses there.
And the scanner is powered from mains power, so we cannot blame
a USB fuse blowing as an excuse for non-operation.
Paul
https://help.ubuntu.com/community/ScanningHowTo
[see Sharing a Scanner Over a Network - 1) The scanner is connected a
computer - the server - and shared over the network.]
Raspberry Pi server ? Scanner ? VOIP ?
Oh, the possibilities. :-)
What I'd like to see, is your udev working properly when a USB
item is hotplugged. There is a logging system, and a way to turn
on or adjust logging for udev. Keywords udevadm and journalxe or so.
I'm just surprised it's so hard to get answers from the machine.
I really used to like looking in "dmesg" and seeing a breadcrumb
waiting for me. dmesg is not what it used to be. It's been
tampered with. I've even had cases recently, where dmesg would
not run. Years ago, it always worked.
As for the scanner types, I'm surprised someone has not piped
up and suggested replacing the scanner. I'm not even sure a
discrete scanner would be in my computer store today, and it
might be part of an inkjet printer.
The old scanners used CCD. It has depth of field. If you lay
a bound book on the scanner, it tends to photograph "some"
of the words as they curve at the binding. Modern scanners
are mostly CMOS, the focus is sharp, the depth of field is
poor. If you lay a bound book on the surface, a modern scanner
records words near the binder as a grey blur. That's the
difference.
For sheet fed stock, the CMOS is fine, because you can press
the sheet firmly against the glass. But any time the target
won't stay on the glass, there's a possibility the CMOS
won't register the item well.
I would prefer your USB to be working, so any future USB items
will also work. In hardware, things always start with a PCI block,
the USB logic block would be under that, and the USB PHY then
connects to your device. It really should not be flaky. The PCI
driver handles either PCI or PCI Express. While it might say
PCI, the bridge could actually operate at 32GB/sec if necessary.
They design the hardware blocks, to "look like" PCI, so a bog
standard driver can do the work.
You can try "lspci" and see the mess that's in there, if you
want some idea of portions of the next layer up. and I'm referring
to bits of stuff inside the Southbridge, where at least some
of your USB ports live.

I use mostly laptops nowadays so no SCSI interface. I don't even think
my desktop computer has SCSI interface.
HP ScanJet Scanner came with PrecisionScan Pro Software CD (for Windows
95, Windows NT 4, or Windows 98 operating system).
I guess my scanner server would have to be an old Windows 98 ?
Did any Ubuntu LTS ever support my HP ScanJet ? Ubuntu 10.04 LTS was
the first version I started with. No wonder I had so much frustration
with scanning. :-)

I would start by doing a color scan.
This will prove the one-pass scanner really works.
The reference to 'Serial'='sane:hp:libusb:001:042' does not imply RS232 serial port,
it's a kind of reference to a serial number. Which the unit might not have. Typically, USB devices are supposed to have serial numbers, which allows moving the connector to another port, without clogging the detection
records
with excessive "same-entries".
You can probably do a color to gray transform in GIMP or something.
Image : Mode : Grayscale . It's better than getting no scan at all.

I would start by doing a color scan.
This will prove the one-pass scanner really works.
The reference to 'Serial'='sane:hp:libusb:001:042' does not imply RS232
serial port,
it's a kind of reference to a serial number. Which the unit might not have. >> Typically, USB devices are supposed to have serial numbers, which allows
moving the connector to another port, without clogging the detection
records
with excessive "same-entries".
You can probably do a color to gray transform in GIMP or something.
Image : Mode : Grayscale . It's better than getting no scan at all.

For simple-scan, the only option is Text or Photo, so I selected Photo after starting the scan app.

If there is a transport screw, make sure the transport screw is
in the free-to-move position. Mine has a transport screw, that will
prevent the scan head from moving.
There does seem to be a USB bandwidth issue. Some sort of behavior triggers at >200 DPI setting. Do a scan at lower resolution. I don't think this will help, as I suspect something else is wrong.

I was not able to find any "transport screw" but I saw a Lock/Unlock latch (for the ADF?). When I locked it, then try to scan, it made a scary clicking noise so I quickly unlocked it and unplugged the ADF, which I don't use.

Why?
Use Wireshark, and record the traffic of the session. See
if by accident, you are reloading the groups list or something.
The groups list is several megabytes.
Other than that, you may have some software set up, which is
making your newsreader connect unnecessarily. And "running up
the bill". The server has something like 1200 connection per day
limit. It's probably in that ballpark. There may also be a
bandwidth limit.
If you've tried to attach pictures to a post, and you did that
enough, that might cause a problem.
If you use Port 119 while carrying out the session, two things happen:
1) Your password is sent in plaintext. This is bad. Relatively speaking.
2) By running on Port 119, the messages between you and the server
are in text format, and easier to read in Wireshark. This is good.
If you run on a TLS connection, then Wireshark will not be able to
display english text for you. It'll be protected by TLS. All you would
know then, is that "gobs of something" are going to the server.
Whereas on Port 119, you'll have more opportunity for analysis.
You can save Wireshark traces for later if need be.

If the driver has a call-back, indicating the page is

maybe it's not happening.
When you scan your single sheet, do you lift the ADF,
and put the material right on the glass ? If so, the
ADF should sense you are not using it. There should be
a switch somewhere, that detects the ADF is in position.
If the ADF is out of position, it should not be

which is able to detect scanner since I am able to get to the Scan button. >> Error popup message is...
"Error during read: Error during device I/O."
In Windows, HP scan software also failed. Same popup message as before.
Then, I got a scan again with Simple Scan...
Simple Scan Output - Photo (good), then Text (fail)

[Two consecutive scan attempts.]
The code appears to be written in VALA (seems almost C++ like) and
translated to C code.

[+253.14s] CRITICAL: scanner_set_int_option: assertion '_tmp1_ == SANE_TYPE_INT' failed
Now, is that message fatal to the mission or not ? That's what I mean
by not putting information in the log, that a user can rely upon.

^^^^^
That's casting the float to an int, which should have worked.
https://valadoc.org/glib-2.0/GLib.Math.round.html
What bothers me about this GLib thing, is there's an attempt to cast to (int) that seems to be getting ignored somehow. Then there's an assertion when
some piece of code decides the thing passed was still "double". Presumably this is known at one of the two "compile times".
I mean, you can smell trouble, when some of the other modules have
instances of (double) DPI and (int) DPI. And you know at some point,
type conversion has to happen. And you've got this strange language,
and you have no idea how "robust" this crap is. Erg.
Wanna know why your scanner doesn't work. Read the first paragraph
of how to make sausage.
https://en.wikipedia.org/wiki/Vala_%28programming_language%29
If it was written in C++, I wouldn't be nearly as concerned. As C++
has had a lot wider audience, and lots more eyes applied to it over
the years. I have no idea what the track record of GLib is like.
*******
I like your evidence-gathering, as it means the thing is still usable.
But how to crawl out of this mess ?
