SCUF Vantage Wired/Wireless Controller for Sony PlayStation 4 and PC retail - Silver

Product Name: SCUF Vantage Wired/Wireless Controller for Sony PlayStation 4 and PC retail - Silver
Hello everyone. I genuinely don't know how to test this controller. When I connect to a pc and switch it to usb ( on the bottom left of the controller ) it does nothing. Then I switch it to Bluetooth ( bottom right of the controller ) and it doesn't nothing. Not sure I have download drivers or update it or connect it via steam or sync it or what. As is untested. What I can say is the L2 doesn't have the trigger retail stopper.. Open to offers. Thank you :).
