The game requires additional tinkering to get joysticks to work in addition to the setup required on windows. When using config files copied from windows, I had joystick issues like were described in the other reports. Stickig, drift, etc.

I took the following steps to enable hidraw based on https://github.com/ValveSoftware/Proton/issues/6839

1. Created a `/etc/udev/rules.d/60-steam-input.rules' for my devices:

KERNEL=="hidraw*", ATTRS{idVendor}=="3344", ATTRS{idProduct}=="8197", MODE="0660", TAG+="uaccess"

KERNEL=="hidraw*", ATTRS{idVendor}=="231d", ATTRS{idProduct}=="0125", MODE="0660", TAG+="uaccess"

KERNEL=="hidraw*", ATTRS{idVendor}=="231d", ATTRS{idProduct}=="0127", MODE="0660", TAG+="uaccess"`

2. Used launch optons to enable HIDRAW for devices: `PROTON_ENABLE_HIDRAW=0x231d/0x0125,0x231d/0x0127,0x3344:0x8197 %command%
3. Rebooted.

All joysticks are working as desired.
