On Model 2 it says to click the checkboxes for steering brake and accelerate and then you double click and it opens a box that has a drop down where it should see your wheel to choose. My issue is as soon as I double click to get that next window with the drop down it crashes. I read something about M2 crashing if you have a lot of usb connections.
I will check on the Model 3 Supermodel version but it has a GUI where under controls there are 4 tabs basic, gun, race and other. Then when I go under race it has columns button 1 2 3.. I will take a pic when I get home.
