not sure if it's old or new, it was just given to me, it connects through a usb cable thoughNew or old type?
Connecting via cable or wirelessly?
yep, tried it on 2 different PCs, same thing happens sadly, it really is the connection though I think cause every button works perfectly fineI have never run across a significant issue with either generation of Xbox controller (or clones) connected via cable. I would suggest that the controller is probably bad. Do you have another PC you can try to connect it to just to see if the issue follows?
