USB mouse lockup

USB mouse lockup

[John Wong]

While in X, the mouse all of a sudden stopped working.  This is a usb
mouse on 2.6.0-test4 on a nForce2 system.  Previously, when I had this
problem on 2.4.21-x when the various nForce2 support was being worked
on, my temp fix was to remove the ohci-usb module and reload.  I haven't
run into problems in 2.4.22.  With 2.6.0-test4 however, when I try
remove the usb module, I got this:

Can you enter this into a bug in bugzilla.kernel.org so it gets taken
care of?
