I have a big problem I played Fortnite with my friend a little later the controller just went out I can connect it to my cell phone but on the pc USB device was not recognized I plug the USB cable into my old broken controller and it works I have replaced the battery everything already tried it is simply not recognized what can I do do I have to buy a new controller now?
I'm afraid. You already excluded cables. For security reasons, you could try the controller on another USB port (ideally also try another USB controller, so if you have USB2.0 and USB3.0, then switch to the other standard, so that you will definitely change the one Controller). Or test it on another PC.
But mostly this is an electronic error if Windows recognizes something, but the two can no longer negotiate with each other what it is.
