I'm leaving this code in here for posterity, and because maybe it can be used on other platforms. But using the DS4 on the Wii U directly is impossible because it doesn't generate a HID event. Which makes me think it's not a HID device at all–at least, not over USB.

I imagine it might be useful in Bluetooth mode, though.
