Please describe your issue in as much detail as possible:

In my Reddit post there's my whole short story.
I tried setting them up from the Steam Controller page, but it requires me to push buttons. The axis are recognized as such, but then I can't really go forward or skip. Closing the window the first time has also given me a Steam crash.
Games ignore them completely.
