When installing my Steering Wheel and Pedals for my driving games.
In the "Set-Up" program for the Controller Hardware, the program asks me if the "Pedals" are "Separate", or "Combined"....
...for example;
Are
both the Wheel and Pedals connected to the same Socket via a single cable, or is the Wheel connected to one socket, and the Pedals connected to a separate socket on the Computer?
In my case, the Wheel and Pedals connect to a single USB Socket, so they are "Combined"..
If the wrong "Separate/Combined" option is selected the arrangement will not work correctly!
If you are using a separate Joystick/Yoke and CH Pedals plugged into different Sockets, make sure they are selected as "Separate"....and not "Combined"!
Give that a try...
