If your controller is the wireless ones then you will need a 3rd party usb adapter that will pick up the signal from your controller, if its wired then just plug it into ur usb port. USB carging wires wont work as it is just sending power through.
After being able to connect your controller to your PC you will need to use a program called xpadder, you can assign keys to the buttons ect.
Using a controller isn't recomended becoz u will have no aim assist and u'll just get mad over getting raped. If you're getting into PC then get used to mouse+keyboard.
