After the game was released it occurred to me that the H-shift lever on the Logitech 920 steering wheel did not work at all. After searching the forums I did not find a solution to this problem until I started trying things and finally found the solution.
I play with a controller connected to the console to have the audio in the headset and the problem is having the controller connected from the beginning.
The solution is to first connect the steering wheel to the console and turn it on from the button on the steering wheel. Then you must start the game and just before you start the race, connect the controller to the console to have the audio.
Attention: If you disconnect and reconnect the controller in the middle of the game, the H shifter will stop working again.
I hope it helps you.
