USB is pretty hosed. :-(

For a while, removing the mouse didn't get detected and you had to kill moused
manually.  Then the removal event happened.  A new moused would start but it
was impossible to kill -9 the old moused.  If you remove the mouse again, it
instantly panics the box.  I've not seen what is happening as I've always been
in X at the time. :-/

Cheers,
-Peter
