    Hi
    purchased and used an external 2.5" Hard Drive

    now when i plug into my computer XP gives me this message - Unknown USB device. USB has malfunctioned..The USB device is reported to have malfunctioned and is therefore an 'Unknown Device'.

    it does work as i still use it in other computers,

    so far i have:
    Unistalled all usb controllers & reinstalled
    used system restore back to when they were working

    * from device manager here is my USB devices.

    SiS 7001 PCI to USB Open Host Controller
    SiS 7001 PCI to USB Open Host Controller
    SiS PCI to USB Enhanced Host Controller
    USB 2.0 Root Hub
    USB 2.0 unknown device
    USB Root Hub

    Is it possible to reset the settings in the usb contrller / registiry to get this working again

    thanks

    i have solved this...

    turned off und unpluged all usbs (plug mouse to port)
    leave off for about 30mins
    reboot in safe mode
    goto device manager
    uninstall all usbs - start from the bottom & work up.
    reboot in normal mode
    give comptuer time to reload the drive required

    now you should be fixed -- worked for me --
