seems like a driver problem to me ... and ya u have both usb 1.1 and 2.0 connectors so in your bios what speed is the usb running at ? hi-speed or full speed ? hi-speed is around 480 mbps and in for usb 2.0 but if u are using this option then usb 1.1 devices wont work... check this out.

also try installing all the usb drivers again. uninstall them one by one from device manager and install again (xp will install them automatically).

well...there aint a setting for usb high speed or full speed simply coz usb 1.1 works at 12mpbs and 2.0 at 480mbps depending on the device and the port to which it is connected to. i'll try reinstalling the device drivers and get back..

thanx for the reply...
