xb76x2u: Xbox One wireless adapter v2

blee

Hello boyos,

I didn't see an existing topic on this so I'm creating this for visibility. I suspect the xb76x2u driver implementation is incomplete and so the Xone v2 adapter will not function. I noticed this when I spun up retropie on a rpi 3b when I was unable to pair the controller by pressing the pair buttons on the adapter and controller.

Here's dmesg:

It's also entirely possible that I'm an idiot and didn't set up some corresponding udev rules. But so far my web searches only uncover people with the same issue running the latest Linux kernel (Archlinux).

And I'm fully aware that some people run Xone controllers via bluetooth. That's a fine workaround, although personally I have one of those snes knock-off wired controllers so I'll just stick to using that for now.

Also I think this is my first post. Kudos to this project, and high five! I love it.

You can try the Xow driver for these kind of dongles - https://github.com/medusalix/xow

@mitu I can confirm that works. Thank you!
