soheb, (edited ) I'm trying to get one of my Xbox Series X controllers working on the Steam Deck, but I need to do a firmware upgrade to fix a problem of the controller not registering properly on Steam Deck.
This means:
- Downloading Windows 11 on my Macbook because I don't have any Windows devices.
- Downloading the Xbox Accessories app via the Microsoft Store (which I guess will need a Microsoft account).
- The firmware upgrade.
Meanwhile, my PS4 controller just works.
