SNESDev is only needed if you directly connect SNES controllers to the GPIO pins. If I understand correctly, this is not the case here.

First of all, you need to check, if the OS identifies your USB-adapter correctly. You can check this, e.g., with the commands lsusb or dmesg.

Then you need to know whether the adapter registers the controllers as joysticks or as a keyboard in the system. Depending on that you then need to configure the inputs for the Emulators.
