Does RasPiOS have any utilities to monitor usb activity
and errors? FreeBSD has something called usbconfig, but
nothing by that name is found via apt search on the Pi.

The first place I'd look is in syslog (/var/log/syslog), then maybe
dmesg but that may have no more than syslog.

USB access, errors etc. get logged in /var/log/messages so you can see all
the gory detail of USB activity by running something like:

sudo tail -f /var/log/messages | grep "USB"

which can be very useful for debugging. However, If I wanted 24 hour
monitoring of selected USB activity, I'd install the logwatch package and
write a logwatch reporting module to capture exactly the detail I want to
see. For instance I did that to report activations of the UPS that
supports my house server and internet gateway. This setup by default sends daily reports to root on my house server, which is configured to forward logwatch reports to my usual login on a laptop. Logwatch modules are traditionally Perl scripts but I don't think there's anything preventing
you from using awk or any other compiled or scripting language instead.

USB equivalents of Wireshark, the TCP/IP message analyser/scanner, may
also exist: I haven't needed them so haven't looked.

Last time I looked (admittedly some years ago), Wireshark itself did
USB captures. The decoding was rather rudimentary, though.

So Wireshark is the first place I'd look. If it runs on RasPiOS, of
course.

Much to my surprise there was nothing in syslog and very little
by way of dmesg | grep -i usb, all of it device discovery during
boot. I guess that means USB works without problems......

Monitor as in actively, or the current state? If the latter, then lsusb.
See man lsusb after installing (not sure if it already is in the Lite or
Full distro). Try:

lsusb
lsusb -tvv (tree view can have 0, 1 or 2 v's but doesn't need sudo)
sudo lsusb -vs 2:2 (first external usb3 device)

See man lsusb after installing (not sure if it already is in the Lite or

Restrspectively, as in how many errors (and on which device) since boot.
Bonus points for what kind of errors.

lsusb
lsusb -tvv (tree view can have 0, 1 or 2 v's but doesn't need sudo)
sudo lsusb -vs 2:2 (first external usb3 device)

Looks like it's already installed. But, lsusb seems to report
what devices are present. I don't see an option for seeing errors.

Thanks for writing!

Have you seen and/or captured any USB errors so far? If so, note which
logfile they are written to (probably /var/log/messages since that is
where connect/disconnect USB messages go on my (Fedora, not Pi) systems,
and keep a copy of at least one.

Then write a logwatch report script that reports matching messages. I'd
try an awk script for starters ('sed & awk' is a very well written
O'Reilly book and awk is a scripting language that was designed for
quickly producing custom reports from file content), but you may prefer to
use Perl or Python.

Never on RasPiOS. I'd like to use it as a point of comparison.

Perhaps it's a wild goose chase.....

Enable usbmon in the kernel. Google is your friend.
