My new USB mouse (a Logitech G5) works fine both in the console (with 
moused) and under X (both with moused and directly)... For the most part...
However, once in a while it just dies (the lights indicating the DPI 
setting on top and the lights underneath it goes off and it stops 
Since, according to the ehci man page, the USB 2.0 driver is quite 
buggy, I tried disabling it, but the problem didn't go away.
I've also tried connecting the mouse to different USB connectors without 

Every time it happens I get two lines in the /var/log/messages file:

Aug  6 01:03:50 trapper kernel: usb1: host controller process error
Aug  6 01:03:50 trapper kernel: usb1: host controller halted

Now for my questions:

Does anyone have any suggestions as to what causes this?
The mouse itself?
The USB host controllers (then all four controllers on my motherboard 
are faulty)?
Buggy USB driver (if that is the case, both ehci and uhci are buggy)?
Any other possibilities, that I haven't considered?

I'd apprectiate any help, since this annoys the hell out of me.
