Describe the bug
I have an Azeron Keypad that I use to play minecraft, and I'd like to use the 'joystick' for analog movement.

When it's plugged in, it is recognized as a controller, but for some reason, it won't let me change the key bindings in the UI. Only my Xbox Controller can update key bindings.

Additional context

The orange text indicates missing mappings, try creating one using gamepad-tool (https://generalarcade.com/gamepadtool/) and paste it into the Custom Mappings section.
If that works, you might as well want to contribute the mapping to https://github.com/gabomdq/SDL_GameControllerDB so other people using the same Controller don't have to do that themselves.
