Public bug reported:
Binary package hint: kernel-image-2.6.15-26-386-di
I have a PS/2 mouse and PS/2 keyboard.
Plugged in USB camera (Canon EOS 20D). Everything works fine.
Remove USB camera (removed cord at PC end). Mouse pointer disappears in X.
CTRL-ALT-Backspace to restart X got it back, but I had to kill my X session.
Boo.
Presumably a bug in the input layer, as USB had nothing to do with my
mouse.

Noticed later the mouse pointer was not there (was using another PC).
Tried removing and inserting PS/2 mouse (which didn't help) before I
restarted X.
