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.

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...
