More info about the issue I am having with the 950Q, This device works perfectly in Windows Media Center which I do not want to use since I have set my PC up with MC 14. I have pasted the logs below. In the logs it does say the device is in use but I don't know with what or how since the PC is freshly booted and nothing else is running.
