I have a Tyan S2099 mainboard and have been having USB problems for awhile. I have 2 USB 2.0 ports in the front of my computer, and one of these will not respond when I connect a device. The other one will sometimes cause the machine to lock up.
I opened device manager (Windows XP) and then "USB controllers", and I see an "unknown device". When I look at the driver for this device, I see that there is "none installed". Could this be the cause of the problem?
I didn't find the right solution from the Internet.
Refresh USB Ports
Use Drive clean up to remove USB device drive info from the registry
click here device manager Uninstall EVERYTHING under the heading USB,
reboot the PC let XP find and install new hardware.
Your equipment should now be recognised.
fruit bat is right , go device manager and right click/uninstall all usb devices , when the pc restarts windows will re-install its generic drivers , am I missing something though , why did you post under heading system restore problem.
