I have a MouseSystems mouse too (made by "A4 Tech") and I've
noticed that it's acting erradically recently. I doubt that the actual
MOUSE can somehow get "broken"...it's worked great for years in several
computers. One thing that worries me is that recently, linux seems to
detect one of my serial ports as an 8250 (it's really a 16550). But this
port isn't the mouse port. But it's still suspicious. (Could it have
something to do with the fact that there's a hewlett packard remote
control receiver plugged into that port?)
I've also noticed mouse detection failures when NT starts up.
So I'm guessing either Linux is doing something REALLY phunky
with my com ports, or I've got a hardware failure somewhere. :(
If anyone else has been having problematic mice, it'd be prolly
best to let everyone know...
