I know AH has it's own programming utility for joysticks, I've tried, but I cannot seem to be able to make AH recognize anthing more than 1 joystick's worth of buttons.
Hopefully, I can use AH in this way, and I'd rather anyway as there is a slight delay with the CH control software.
edit: I have a CH Prothrottle, CH Propedals, and a CH Fighterstick.
Generally, it only reads the whatever stick is listed first on the joystick list.
