Angels have the Phone Box
Does it show in device manager? Perhaps with a bang on it? If so, please uninstall it completely (right-click and select uninstall) and opt to remove all drivers if it gives you that option. Reboot. Go back to device manager. Hover over it and select properties. In the general tab, see what the error description is. Mine had an error of "device not installed". I had to keep deleting the device from device manager and rebooting until it finally showed "can not start", and the reason was no driver installed. I was then able to install the driver.
