Thrustmaster T150 (t150_driver) not detected by games, but works in Proton wine control panel

I'm trying to use my Thrustmaster T150 wheel with Steam Play/Proton, but my games do not detect any inputs when I try to assign inputs.

Games:

• Project Cars 2 Demo
• Automobilista 2

Proton 6.3-3
T150 driver: https://github.com/scarburato/t150_driver (master a47b1bcb0e8aeee9af8acd36ee83aee923ecd82b)

Project Cars 2 Demo proton log of launching the game and trying to assign keys by pressing on buttons on the wheel.
Launch options: WINEDEBUG=+dinput,+joystick PROTON_LOG=1 %command%
steam-737770.log

I have tried connecting an Xbox controller and the inputs are correctly detected by the games. When I have tested, I have had only one controller connected each time (and I removed the Wacom tablet that produced an extra /dev/js*).

If I launch "wine control", with the Proton wine, and open Game Controllers, I can see that both the controllers appear and wine reacts to the inputs.

Running "proton-joystick-debug.sh.txt control" (aka wine control with correct environment) I can see that Proton wine detects the wheel correctly and both analog and button inputs work. Here I am pressing some of the buttons. (One device is shown, which is the same as what happens when I plug in an Xbox controller ("Normal" wine shows two devices for each controller: joystick + event))

Here are logs from opening wine control -> Game Controllers -> Test Joystick, with WINEDEBUG=+dinput,+joystick
Thrustmaster T150: wine-t150-test-joystick.log
Xbox gamepad: wine-xbox-test-joystick.log

lsusb -v
lsusb-v-t150.txt
lsusb-v-t150-sudo.txt

Any ideas on how to fix this? Is there a whitelist somewhere?

Begin with the Proton +dinput,+joystick launch log and compare it with the working wine control logs, then inspect the linked t150_driver revision. Reproduce the issue with the listed games and Proton 6.3-3; done means the T150's buttons and axes are detected during in-game input assignment as the Xbox controller is.
