to ontroller users;
While searching for a way to properly connect, I found the following link.

All you need to do is overwrite the mu3hook.dll file into your game folder, and switch your ontroller to WINUSB mode.
In my case, this wasn't connecting properly, so I ran the game with the ontroller unplugged, plugged it back in after the game was fully running, and it works perfectly fine.
LED works perfectly as well, except for the side buttons (if you want to get the LED on the side buttons to work as well, see the link).
I hope this helps other ontroller users.
