Your joystick USB and your pedals gameport with work in AH ,, CFS2,, FS2000 or Fly2K or MigAlly . Games that let you have more than one controler at the same time .
Plug your stick into the USB port . Plug your pedals into the gameport . Get them both working ok in game controlers ,,,,,only they will be separte .
Then in AH go to setup , joystick , select joystick , and setup BOTH your controlers .
Tells you more on the AH website in help section .
This will work in AH , I used it for quite some time before buy a Saitek rig .
DRILL the isn't any check box that will "enable rudder pedals" with a PrePro joystick . It has it's own separte driver . Hoffman gets his to work with a adapter like xmab said , they will work in any games and are very well made . But they do cost lots and come from Germany , like it was 37 USD to Michigan
