== DETAILS When I first implemented the Wii U HID architecture, I ended up having to design my own implementation because, at the time, I did not have a way to read the HID device string to allow the existing code to successfully detect the gamepad. After spending some time experimenting, I've figured out how to do this. And that means I can better align the HID driver with other platforms. change summary: - create a single state structure for all three sub-types of wiiu pads (kpad, wpad, and hid) - eliminate confusing duplicate pad lists - eliminate confusing duplicate HID pad drivers (ds3, gamecube adapter, etc) - ensure the ds3 driver still works
