Valve released a new Steam Deck Beta update that includes a useful tweak to its Xbox controller detection.
There’s a bit of a problem with modern Xbox controllers and Bluetooth, where they won’t properly connect up with SteamOS / Linux unless they’ve gone through a firmware update. I’ve seen a lot of support requests about this issue over the years and so it’s good to see Valve highlight it directly. While it’s a Steam Deck Beta Client update, it should apply to other SteamOS devices too.
I’m almost entirely sure that PS4 and XOne controllers did get upgrades at some points. Definitely Switch 1 ones, which matters or not depending on how you split the gens. There were definitely revisions in older controllers, though. Some were labeled and had obvious new features, some were quieter. And PC-side drivers got updates all the time, obviously.
Also, your current gen controller will also keep working indefinitely without an update. In this case Valve is annoyed about a particular dependency where THEY need the upgrade to happen for a feature compatibility thing, but the controller proper will work if you plug it in.
