I have tried to play black ops 2 on pc with many different controllers including a xbox usb made for pc and a ps4 controller with ds4 but black op 2 doesnt recognize any of them. I have tried validating the files and re-installing it but it didnt work. Also when I try to use my controller on rocket league it recognizes my controller as player 2 and puts me in split screen when I want to play as a primary with my controller. I think my pc might be setting my controller as a secondary device somehow im not sure. When I plug my Xbox controller it also shows up as player 2 on the controller itself. Please HELP!!!
