I have been running Kubuntu 9.10 on my Toshiba Satellite laptop. In the past, the USB mouse I normally use with it would not sync up and it would not move the cursor on the screen. On those occasions, I could reboot and the mouse would work.
Just recently, the USB mouse will not work at all, even after a reboot. I did a search in the database and did not find any similar problems. I check the /var/log/dmesg file for USB messages and found the following USB references:

I have a dual boot system with 9.10 and Windows 7.
It is probably only coincidence, but the failure occurred after an episode on Windows 7, where
I introduced an external USB drive in the Windows environment. After a day, the USB external drive failed and when I researched the problem on the internet, I found that Microsoft has a known bug with USB support on 64 bit systems. I have to wonder if there is anything on the USB controller that can be set by the Microsoft driver that would effect the USB controller on both Windows 7 and Linux. Hmmmm?
Is there anyway to reset the Linux USB driver configuration?
Thanks in advance for any suggestions.
