The Xbox 360 controller has the same basic familiar button layout as the
Controller S except that a few of the auxiliary buttons have been moved. The "back" and "start" buttons have been moved to a more central position on the face of the controller, and the "white" and "black" buttons have been removed and replaced with two new bumpers that are positioned over the analog triggers on the back of the controller. The controller has a 2.5mmTRS connector on the front, allowing users to connect a headset for voice communication.[5]It also features a proprietary serial connector(which is split into 2 parts on either side of the headset connector) for use with additional accessories, such as the chatpad.
On August 31, 2010, Microsoft's Larry Hryb (a.k.a. Major Nelson) revealed a new design of the Xbox 360 controller set to replace the Wireless controller bundled with thePlay & Charge Kit. Among small changes such as the shape of the analog stick tops and grey-colored face buttons, the new controller features an adjustable directional pad which can be changed between a disc type D-pad or a plus shaped D-pad. The control pad was released in North America exclusively with Play & Charge Kits on November 9, 2010 and was released in Europe during February 2011.[7] The Xbox 360 controller provides a standard USB Human interface device
software interface, but is designed for the Microsoft XInput interface library.[8]Although many PC video games support the XInput library, some games might not work with this controller.
