Works great. Your computer or you don't know how, here are a few steps. Press and hold the power button on the Xbox controller for a few seconds. On the top of the controller, between the bumpers, is a small button next to the cable connector. Press it for 3 seconds. The Qumox receiver has a similar little button, press and hold for 3 seconds. The light on your controller should flash quickly, and if it does, you're paired.
