3 years ago So, I managed to make this work.
You have to edit the retroarch.cfg and retroarch_default.cfg file in /etc/libretro and /etc/libretro/config.
You have to set input_menu_toggle, input_menu_toggle_btn, input_exit_emulator and input_exit_emulator_btn to "nul" in the default file, then in retroarch.cfg set all of the above also to nul except for input_exit_emulator_btn to "8", and it should work as intended with the RR plugged in USB
I use the 8bitdo Retro Receiver via USB and use the SNES/NES Switch wireless controllers with it. When plugging the RR to the front port directly, it is recognized as Clovercon and Select + Down works as intended in RetroArch. When plugging the receiver in USB via an OTG hub however, it is recognized as a "Microsoft X-Box 360 pad" and Select + Down opens the Retroarch menu instead of going back to home. I've tried fiddling with the config files and in the config menus directly, but I wasn't able to make it work.
