Well I just checked your device ID file and I have the basic standard one so I have no idea what my problem is now. :(

OK so after days mucking about with this dongle..... set your driver to switch from usb2 to usb3 and inserted it in a rear usb3 port (was previously using front usb2 and usb3 ports through various troubleshooting attempts) and it worked so well the wifi even came up before my NFS mounts!
