There are a number of force feed back codes which can be written to the USB out-port, some of these are know/understood but assistance is required to further reverse engineer the rest.

The effects are upload into 'slots', these are continuously sent over the wireless link. The wheel is capable of supporting 4 simultaneous effects, plus an additional auto-center effect. The selected slot for an effect is encoded into the 1st byte of the out-port write.

The Force Feedback configuration is sent continuously over the wireless link, which takes the form of a 31 byte payload. The wheel is capable of supporting 4 simultaneous effects, plus an additional auto-center effect. The various effects are upload into 'slots', the format is as follows:

The type of effect is encoded in the second byte of the out-port write, with specific settings for the effect in the further bytes.
