My USB mouse recently started giving me phantom scrolls (movements of
the mouse wheel, even I made sure the wheel was in a resting position)
in recently kernels. It happened too infrequently for me to care.

Bus 001 Device 004: ID 045e:0047 Microsoft Corp. IntelliMouse Explorer 3.0

My USB keyboard also occasionally loses all contact with the number pad.
Other keys continue to work as expected. Unplug/replug sometimes
helps. Reboot /always/ fixes the issue.

USB HID is a fun place to be.

Whee...
