I used speedkeys with a analog stick , not usb .
About the 568 model if you don't know if you have it or not most likly you don't . It has the same base at the "FIGHTER" stick , more elect. stuff I guess to let more than one button work at a time .
Don't know why speedkeys don't work for you . What do you use for a throttle ?? I used CH Pro Throttle , analog . I had to use the speedkeys program to set the buttons up on it . I know on the CH website they list one soundcard that doesn't have enough "stuff" to work right with their products , don't remember if yours was the one or not . Maybe you have that sound card ? Hate to tell you to get the throttle and still have problems

The throttle is damn nice though .
OK CH guys , I am out of ideas . Kieran is a CH guy , Ammo , Popeye also . I was but am using Saitek with USB Ch Pro Pedals with Bob Church's rudder driver .
PS: I know one time I had all the button working with that driver , but the second hat was only four more buttons I think . I still have it , I checked but ain't using the stick anymore , got to spiking when I pulled back .
