Hi.
I have problem with my Thrustmaster Ferrari 458 Spider steering wheel in FM7. When I connect wheel to Xbox and start FM7 using buttons on that wheel, game is loading to main screen, where non of the buttons on wheel are working, no respond from buttons. I can’t do nothing(wheel is working fine on xbox dashboard). When I close game, connect standard gamepad and start game again, there is no respond from buttons on both controllers…My steering wheel is working fine with FM5, FM6 and FH3, just start the game and play.
Yesterday I have found solution for this. To play on this steering wheel I must start FM7 normally using this wheel and wait for main menu in game. Then logout from Xbox, login again, close FM7 and start game again. After that everything is working but in my opinion it shouldn’t be so complicated to play with steering wheel 
That doesn’t sound like much of a solution, more like a work around. I cant get my wheel to work either.
I start the game with my wheel. After that, I turn on the 2nd controller for sound. Works great for me.
Unfortunately this doesn’t work for me. When I connect standard gamepad still nothing, both controllers aren’t working in FM7. Only logout/login is solving this problem. This is very annoying.
I have the same issue but i havent got the wheel to work in-game same wheel
