    You can try this:


    Alternatively, removing all entries relating to USB in Device Manager and all associated USB drivers will force 7 into refreshing the USB driver stack.
    Begin by unplugging all USB devices, then use Add/Remove Programs in Control Panel to uninstall any USB driver software.
    Next, boot up into safe mode and go to Device Manager. Once in device manager make sure 'Show hidden devices' is checked under the View menu. Uninstall all device entries in this order;

    1. USB peripheral devices (printers,etc.)
    2. HID and/or Composite USB (Human Interface Devices) You're using PS/2 input devices so you may not have this entry.
    3. USB Root Hub(s)
    4. USB Host Controller(s) (Universal or Enhanced Host Controllers) Then boot back into Windows (not safe mode) and it should populate the Root Hubs & Host controllers again. Proceed to plug your USB devices back in, starting with your powered hub. Be aware that most USB printers and scanners need to have their drivers installed first before you plug them in.

    Finally, boot back into Windows (not safe mode) and it should populate the Root Hubs & Host controllers again. Plug your USB devices back in, starting with your powered hub.
