I have purchased one of these for my xbox 360, but can't get it to work. I've connected it to all 3 usb ports and subsequently run the tests after each time. each adn every time the tests fail at the first hurdle when it says the wireless adapter is 'disconnected'. How can this be? It's connected!!! The wireless section in the 'edit settings' part is greyed out so i can't edit anything there any ideas?
