USB mouse continually disconnects and reconnects

[Bob Jonkman]

Hi all:  I have a Logitech optical mouse plugged into a USB port.  Evey 
so often the LED goes out, and the mouse becomes completely 
unresponsive.  Sometimes it comes back by itself after a fraction of a 
second; sometimes I have to unplug and re-plug the mouse, and sometimes 
I have to plug it into a different USB connector.

What causes this, and how can I fix it?

For your reading pleasure, I provide some sample entries from my system 
log monitor.  I found these under 'kern.log' as well as under 'messages' 
and 'syslog'.  For these three instances the mouse recovered on its own, 
without unplugging/replugging.

This is currently Ubuntu 9.10 (upgraded daily from a Karmic Alpha6 
install), but it also happened on earlier versions (8.04, 9.04)

Thanx,
--Bob.
