Input: xpad - add support for Xbox 360 gamepad
Browse files Browse the repository at this point in the history 
Xbox 360 gamepad is slightly different then the previous model so it has
its own version of process_packet method. Detection of this new device
relies on USB_DEVICE_INTERFACE_PROTOCOL macro. This device got vendor
specific subclass so it can't be matched with USB_INTERFACE_INFO and
we need only one interface protocol from four availaible. It means
USB_DEVICE can't be used either.

Added xpad360_btn structure with additional buttons for x360 gamepad.
Added xtype into xpad_device structure to distinguish between different
types of xbox devices.
