Expected to be extremely similar to Switch 1. One difference is that over the wire the USB bulk out endpoint is used. Data is sent over interface 1. | |||
Commands start with an ID. All appear to have 0x91 as the second byte. | |||
Axis 1 (left stick up/down) and axis 3 (right stick up/down) are inverted. | |||
