So I finally found this site after about a month of trying to fix my controller problems with my limited RPi knowledge. I bought 2 of these controllers to use.
I plugged them into my computer to make sure they work and didn’t have any issues. However when I have them plugged into the RPi, everything kind of goes haywire. Even with it sitting on the ground, buttons seem to get pressed at random. I ran the JSTest function and that just confirms that the controller is going crazy. Is there a specific driver I need to install? Or could it just be the cheap quality of the controllers?
