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.
Its because the xone dongle uses a proprietary frequency that WiFi doesn’t interfere with. I would have assumed they’d love to ship the Deck with the necessary libs to enjoy wireless gaming. But got’ dayum, they didn’t even think about it. So I had to buy some whack ass 3rd party wired controllers (not 8BitDo those don’t work without some setup) and my kids can now game without my help. And ontop of all this controller nonsense I still have to unplug the AC adapter for the Deck Dock and plug it back in to get the TV to see it after a nap. It would have been easier to buy old Steam hardware that doesn’t have these issues. Still love the Deck tho.
