The above command will only run once when the machine boots, so you
need to have something that repeats this when the keyboard is
(effectively) plugged back in after being removed. Try adding the
following lines near the end of /etc/usbd.conf instead:
attach "kbdcontrol -k /dev/kbd0 < /dev/ttyv0"
On a box that has both a PS/2 and a USB keyboard, I've used an entry
like the following to have FreeBSD switch to the USB one when it
is plugged in, though this isn't what you want if you only have a
attach "kbdcontrol -k /dev/kbd1 -r 250.50 < /dev/console"
detach "kbdcontrol -k /dev/kbd0 < /dev/console"
