SST will be seen ingame as a keystroke command,you can setup the mouse with the majic mouse program!
The I button is a clutch button that immitates a shift function,I have heard that if you leave the controlpanel open in your task bar that AH will "see" the scroll wheel on back of throttle. That was about the only button I never setup,oh and didnt use the clutch either. You can program almost everything ingame without the sst,exception being mouse and clutch,the scroll wheel as I said requires you leave the control panel open.
If your online you can look me up in the training arena and I'll do my best to help you with programing your stick.
