  • Losing keyboard on kvm switch

    From Ted Nolan @21:1/5 to All on Thu Jul 23 15:18:16 2020
    I have my 12.1 box connected to a KVM switch which duplexes the keyboard,
    mouse and display between the FreeBSD system and a Win10 system.

    I find that when I switch to the windows box, it always sees the keyboard,
    but when I switch back to the FreeBSD box, it often looses the keyboard and
    I have to switch back to the windows box and back again several times before
    it will pick it up. I also find that doing keyboard activity during the
    switch back to FreeBSD makes it more likely that BSD will pick it up, but definitely not 100%.

    Is there some kind of harmless background probe I could run on the BSD box
    say every 10 seconds to check if there is a keyboard there? My (unverified) assumption is that switching the KVM back to BSD doesn't generate whatever
    USB signal is sent when you actually plug a new keyboard in so if it decided there was no keyboard during the time it was connected to windows, it won't correct that.

    Anyway, not a big deal, but a minor annoyance. It probably doesn't help
    that I am using a big-barrel keyboard through a ps/2 adapter into a USB adaptor..

    How does the KVM and keyboard appear to FreeBSD when working correctly?

    Hmm, "man ukbd" suggests maybe the kbdcontrol command which I haven't looked into might be useful..

    Possibly test for ukbd0 and if not present, usbconfig -d ugen1.2 reset

    Thanks, i'll give that a try when I have a chance to fiddle with it.
