I have this wheel and pedal and no problems,
i always start the console with the pad,
then plug in the wheel and it does its rotation thing,
then press the ps button on the wheel, a screen pops up asking who you are, just choose you,
then start the game with wheel, and wheel and pad both work in game, as i like driving with the wheel and photos etc with the pad..
Only issue ive had is if i disconnect the wheel from the game, it says controller disconnected etc, and i cant even use the pad then to do anything, have to exit the game, thats usually when ive finished playing anyway..
