Eh. Recently I invited a friend over to play games. I have Linux so it's normal that shit doesn't work but I came across a bug where Steam would just casually take 300% of CPU when Steam Controller was connected and even if I managed to start the game, controllers wouldn't work. I couldn't debug the issue on time, so we did not play games. After she left I figured out that if I first connect the Xbox controller and then the Steam controller then it works, but if it's the other way around then it doesn't. Or in reverse, I don't remember and I'm away from my PC.
