this is with 2.6.4. I switched computers COMPLETELY, and my msnatpro keyboard still
has problems in linux. I come home, and the mouse plugged into it is on, but the
keyboard is out. I unplug/replug(which usually works), and then both are out. I ssh
in and rmmod uhci-hcd, and rmmod locks.
why does this happen after i am gone a while? not to mention, constantly, while I am
using keyboard, it resets(all lights go on and keycodes go screwy) or it just turns
off until unplug/replug.
