	Is the keyboard USB or PS/2?
	It is my understanding PS/2 keyboards (or mice, or anything)
are not required to be hot-pluggable.  Some them, by the grace of
the motherboard maker, are ... but hot-plugging PS/2 has been known
to fry the (otherwise reputable) motherboard.
	If it's USB, then check /etc/usbd.conf.
