Close usb port RRS feed

  • Question

  • Hi,

    I have a device (ACR120 USB Mifare contactless card reader).  Occasionally this device fails locking open a USB port (Port 0) which windows can not release during shut down and therefore is creating a significant support issue.

    We can't disable the device, or the USB bus / controllers through device manager.

    The only way to restart the machine is the hold the power button.

    So now for my question....

    Does anyone know how to force the closure of a USB port or force a mother board to restart without having to call the windows shut down API?
    Its better than fishing a pond
