@arroyjose then it sounds like an issue with the USB adapter rather than a RetroPie/Raspberry Pi problem.

@mitu
I did as told, emulationstation auto config was disabled. I enabled it and also removed xboxdrv.
And it finally works! I could configure both controller, the configuration is kept in the game and even when rebooting I don't need to re-configure it again.

Thanks a lot, the auto config settings were an eye-opener!

@fnkngrv said in 8Bitdo SN30 Pro+ USING USB ADAPTERS - Multiple Controllers:

The controllers are showing in the system as Xbox-360 controllers.
....
I have attempted to use zerojay's controller ID script at least for the LR cores however it doesn't seem to help.

Which script are you referring to ? If it uses joystick names to re-order the joysticks, then having the same name might confuse the script and the order may not be correct.

@BuZz i am running the most recent build of retropie on ununtu 18.04 built yesterday from source.

I see there is an 8bitdo option under retropie settings bluetoorh, that writes to bluetooth rules. I assume this may be the culprite as the docs specify if this is not done the controller would not work on a restart.
