Hello,
My T150 wasn't detected , but I tried to play Project CARS and it wasn't working either.
That was weird, because it used to work.
Then I tried Forza Horizon 3 demo from the Windows Store and the T150 was working ok.
I have found a solution to this type of problem, when the wheel does not work in
games from Steam only, then you should:
1. Go to Steam settings (picture 1)
2. Select "Controller" on the left side (picture 2)
3. Select "General Controller Settings" (picture 2)
4. Make sure that the option "Generic Gamepad Configuration Support" is
not selected/disabled (picture 3)
5. Close the window from picture 3 and all Steam settings.
6. Try to setup the wheel in the game.
I had to select the only Thrustmaster wheel (the last one on the list) in the wheel profiles in the game, to setup force feedback, but in the force feedback drop-down menu the T150 was available.
