Mouse unrecognize on USB port after crash update!

Archived from groups: microsoft.public.windowsxp.hardware (More info?)

Using Windows update, I selected the installation for the A4tech mouse
update! In the progress of installing, I selected continue anyway for the
unsigned driver but it force Windows to reboot! Upon restarting, the
scandisk was carried out. At the login page, the mouse doesnt show response,
so I restarted the windows and it still show the same fault. I unplug the
usb mouse and insert on other USB port and it work! Then I try other device
on the USB port where the mouse fail and they function correctly. Is there a
way to clear the USB port error?
