Please describe your issue in as much detail as possible:

While I know you guys are working on it, just wanted to share my voice. I got the ASUS ROG Xbox Ally X with SteamOS installed on it, and the built-in controlled gets detected as Legion Go's, and surfaces two additional buttons on the back. (L5 and R5)

While this is not a deal breaker, it would be nice to have proper support for the controller.

Steps for reproducing this issue:

1. Install the latest nightlies for SteamOS and Steam client on an ASUS ROG Xbox Ally X.
2. Look in the controller proprieties.
3. Notice additional buttons from a different device are present
