The only way to get that setup to work is if you have two input game card . If you would have had a USB FFB stick then as SKurj said NP but !!!! Don't hook both throttle and that stick together , only asking for problems . One's digtal the others analog .
Buy ya a cheap USB Pre Pro if you have to that works , I use it for my back up setup . Better yet buy ya a Saitek x36 and use your ch peds with it .
cheers spro
