The examples I found in the doc use GetCurrentReading to discover a controller. By asking for a gamepad reading and passing 0 as the device, the function will return an input that matches gamepad and we can get the device from the reading.But when we want to detect another controller, if we pass 0 as the device it will (or can I don't know if it will do it 100% of the time) return a reading for the first controller.I though that I could use GetNextReading or GetPreviousReading but passing 0 for the device in those function makes the function return NOT IMPLEMENTED.
