While I was searching for a USB LED mod that I saw once, I stumbled across a mod in which you make an Xbox controller PC-useable.
It's very easy to do.
All you have to do is tear up an old USB cable, cut/splice all the wires in both cords, and then solder them all togethor. The xbox controller will have a yellow wire, which you don't need, so just leave it alone. It's as easy as matching colors and soldering wires.. lol.

It has functions fully, and every button works as it should. You can even have rumble support.
