identified. If this is displayed (see the examples below)

until you find the NextWindow USB Composite Device.
Close the Properties
screen.
Ensure that the USB Composite device is selected and press the Del key to delete the item
To reinstall the USB device, unplug and then plug-in the NextWindow USB cable.
Wait until the "Found New Hardware" message is displayed.
