The Xbox 7MN-0001 Wireless Controller, was manufactured by Microsoft Corporation. It is the first generation Xbox One controller released, but has since been discontinued. This controller has since been superseded by Models 1697/1698 and Model 1708. While this controller is commonly used with the Xbox One, it can also be used for PC gaming.
Button A does not work on my controller. It used to work when I press it really hard, but now its not working at all. Could it be the rubber pad issue or the board?
