Just a public PSA and was a little sad. I thought the latest kernel updates would address this. Until then, when you plug the official Xbox Wireless USB in- nothing happens.
The 360 Wireless USB adapter still works tho for some reason. 10+ years and its still kicking.
There’s a way to install it, I have done it myself, but I find it annoy AF that it isn’t preinstalled. And then we have to reinstall it each time the steam deck updates.
Thanks for the PSA.
