The attached patch will try to reset the mouse twice to try and wakeup
some KVMs/mice. Specifically, this helps detect some Intellimouse mice
through IOGear KVMs.
Reseting the mouse multiple times shouldn't cause problems, and the patch
makes the second reset non-fatal, however, please try the patch and report
if it causes any problems with detecting mice. I plan to commit the
patch this weekend unless there are problems with it.
Thanks,
Mike
