The xone driver prevents users from using older Xbox (original) and Xbox 360 gamepads. These devices will not be properly recognized in applications, which makes for a pretty crummy user experience.
Full disclosure: I haven't experienced any of these issues myself as I don't have any older Xbox hardware, but have heard reports of issues from folks on the xpadneo Discord.
The usual solution - and what's recommended by the folks on the xpadneo Discord - is to install xpad-noone alongside xone. @ReillyBrogan and I had a brief discussion of how best to do this on T8641. We figure it's probably best to bundle xpad-noone with xone in the xone install. Unfortunately, xpad-noone doesn't have any git tags, nor does it have any release tarballs on Github. This makes it rather difficult to package alongside xone.
