Retro-Bit Legacy 16 2.4Ghz controller not working

[Legomountain14]

Platform: macOS 14.2.1 & macOS 12.7.1

Controller: Retro-Bit Legacy 16 2.4Ghz

When I plug in the controller dongle, I get this message:

This appears to be because the Retro-Bit Legacy 16 acts as a Nintendo Switch Pro Controller, but is detected as "Pro Controller" instead of "Nintendo Switch Pro Controller."

This is my best guess at what is going on.
I did look in the mappings.go file, but found nothing with the name "Pro Controller," which led me to the above theory.

UPDATE: It works on Windows, but not on macOS. Have not tested on Linux yet.

I know that Switch controllers act up in linux (at least on the lakka side), I wonder if something similar is happening here. Does the controller work correctly using mainline RetroArch?

mainline RetroArch?

I haven't tested it yet. I will try when I get back to my computer.

UPDATE: It does not appear to work. I don't know much about RetroArch though.

Ok, I think the issue is the Switch controller driver that is used. This is an issue I have with all of my switch controllers on Linux and Mac OS. You /might/ be able to launch ludo or RetroArch via steam and use it's input mapping instead. I haven't tested that on linux or macOS myself yet.

That seems to be the problem. I have tried the steam method, but it worked once and never again. When I try it on hardwaretester.com/gamepad the inputs appear to just to be random until the tab crashes. This even happens without the controller connected, just with the dongle.
I have tried other switch controllers, and they appear to work fine. The problem seems that it connects via USB.

@bagelbyheart @kivutar is there anything we can do?

[bagelbyheart]

@igoracmelo ludo relies on underlying controller support from the operating system, so if there isn't a working driver we can't provide a mapping. =(
