Installed SteamOS and Joysticks stopped working

Weirdest shiii I’ve ever seen. When you boot it up, only the left Joystick will light up, the right won’t. When I‘m in the OS, not a single button works, besides the off/on button and the Volume buttons. It doesn’t do that everytime tho, but when it works, it only does until I turn it off/go in standby, never during gaming sessions. Anyone with the same problem, or one, who knows how to fix it? Wasn’t ever since I installed SteamOS, only recently.
