When I plug it in, my computer doesn't recognize the device and troubleshooting the device obviously does nothing. I tried it with snes9x and another one and neither seemed to work. The Retrolink SNES USB Controller says that it works without drivers or anything, but then doesn't seem to work with any of my SNES emulators. When you connect your controller on PC, NoxPlayer will automatically recognize your controller and connect it.
There are 6 keys totally in the controller configuration, which can be applied to different games. NoxPlayer provides a set of key-mapping for controller users to match the joystick and make the game more simple and convenient.
