Hi Norbert,
you also might want to look at experimental keyboard mux drivers.
it is based on vkbd(4) and uses the idea of one super-keyboard that
consumes scancodes from other keyboards. there are still a few
issues i need to fix, but, in general, it works.

I back-ported kbdmux to FreeBSD 4.11 (and stopped work on vkbd). It
thanks for your work and patches! i will merge some of your changes into
my version. this way it will be easier to maintain (that is if kbdmux(4)
will be included in FreeBSD :-)
seems to work, although I still have some stability issues with
dynamically attaching/detaching a usb keyboard. For your reference I
would you share with us what sort of issues you are having? feel free to
move this into private email if you are not comfortable discussing it on
public mailing list.
have enclosed a patch file. Sorry for some diffs due to slightly
different coding and debugging style.
no problem. in one of your previous emails you have been concerned about
possible keyboard interrupt miss (in vkbd(4)). kbdmux(4) have the same
issue. is that something you just did not fix yet, or it is not a
problem anymore? in my local tree a added an extra callout that goes 10
times a second and queues interrupt if needed. also i'm curious why do
you use splhigh() instead of spltty()? is this an issue with usb? (not
sure which spl level usb runs on in 4.x)
thanks,
max
