Racing Controllers are used for playing racing games and include a variety of third-party and first-party controllers. Some may lack Linux drivers or udev rules, but there are community efforts to make them work. Some require Windows-only software to configure inputs and buttons.
The best solution is to try your Racing Controller on Linux via the Steam Deck Dock or a Linux PC. If it works and supports xinput, it should work with RetroDECK.
The [OverSteer Project](https://github.com/berarma/oversteer) manages support for multiple steering wheels on Linux. It uses features provided by loaded modules but doesn't provide hardware support.
You'll still need a driver module that enables the hardware on Linux. Most wheels will work but won't have FFB without specific drivers that support that feature.
