Thrustmaster 458 Spider not showing up.

Did you install its drivers? Is it detected by any other game, or by windows itself?

 

I just quickly googled, and I see Thrustmaster does not support this steering wheel on PC. See: https://support.thrustmaster.com/en/kb/104-en/

I'm afraid there's nothing we can do on our side to fix that.

 

This steering wheel is not supported on PC. This means that not even its own manufacturer will dedicate resources to making sure that the wheel works correctly. It doesn´t matter that the connector happens to plug seamlessly into your computer. The fact that it happens to have worked in the past, is a lucky coincidence. It may randomly start working in the future, or it may stay nonfunctional forever. I cannot do anything about that. Maybe some other forum member knows of some trick or configuration to make it work. I cannot help with that unfortunately.
