Emulator

Every time I try to play dolphin emulator with the mayflash 4 port gamecube controller adapter it automatically forces the input down left on both the normal joystick and the c-stick every 5 seconds or so and after some time my controller will start to rumble and a bunch of inputs will start spamming then the adapter will just stop working altogether until I restart my computer and try again. I've already downloaded and installed zadig and done the whole installation process, I've tried unplugging all usb, I've tried disabling audio devices (because I've heard it could be something to do with libusb), I've tried every version of dolphin emulator and I've tried different versions of zadig but nothing has fixed this. I've already spent at least 4-6 hours researching and trying to fix this but nothing has helped.
