Could it be a HAL problem? It's known to cause problems with
peripherials... ;-)

The error message refers to the same device. How is the
laptop's keyboard represented? I thought it would have
been a PS/2 keyboard, attached to atkbd, not a USB
keyboard (as built-in pointing devices are often recognized
as PS/2 mice, being represented as psm0, not ums0).
Additionally, AT keyboards usually cannot be removed,
as they are not hot-pluggable per definition, and in
most cases, they aren't even detected - only the keyboard
controller is.

Can you "dmesg | grep kbd"?

Example from my home system:

	atkbdc0: <Keyboard controller (i8042)> at port 0x60,0x64 on isa0
	atkbd0: <AT Keyboard> irq 1 on atkbdc0
	kbd0 at atkbd0

There is no keyboard connected, just a lonely HIL plug
on the table. :-)

The Sun Type 7 USB keyboard I'm actually using can be
detached and re-attached in X without problems. If the
IBM model M keyboard (can be connected to the HIL plug
if needed) is present, it keeps working, no matter if
another keyboard is attached or not.

NB: I am using X without HAL.
