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.
afaik xone (the kernel driver for the Xbox One dongle) still isn’t part of the linux kernel (neither mainline or steam deck kernel)
the gamepad itself works fine though, only the adapter dongle sucks
since you can also connect the newer Xbox gamepads via bluetooth, it seems like not many people actually care about it
Without the adapter there’s massive input latency.
