I've got one better for ya. :)
I have tried both USB mice and PS/2 mice. The USB port would sometimes jus=
vanish, and to syslog it would look like a disconnected, then reconnected=20
mouse. Nothing was unplugged, and it would do it while idle and while in=20
Switching (using control-alt-F1) to console, then back to X, would "fix" it=
probably by causing X to reopen the mouse.
Now, on the same system, I'm seeing PS/2 issues that appear to be the same=
thing. Switching to console then back to X also "fixes" this. I don't see=
the PS/2 port vanish, but for all practical purposes it becomes dead.
