Yes, the hollow lsusb is what first threw me.  It's always that way, and
/proc/bus/usb is empty as well.

Indeed, it DOES create /dev/input/event5 and /dev/input/event6 when plugged
in, and event5 carries keyboard activity.

So it seems I have two possibly unrelated problems - lsusb &
/proc/sys/bus/usb being empty, and X not recognizing the keyboard.

There's no X config in the 'usual' /etc/X11 location, where does it control
devices like keyboard then?
