@russs15 Thats the exact adaptor I got that never worked with retro pie properly for me. It might be an issue with a driver that changed higher up the chain that's not related to RetroPie itself but raspian, or even in the core linux kernel.
I have several joysticks identified as DragonRise Inc. Generic USB Joystick (one of them is completely new). And joysticks identified as Personal Cummunication Systems, Inc. PlayStation Gamepad. None of them has vibration in PSX games (Vibration is enabled in RetroArch menu and in the game; type of the joystick were changed to analog). Should I install some drivers or what (just curious; I can't say, I really need that)?
@darksavior you can use the bluetooth controllers and the ps3 driver at the same time. Uninstall the ps3 driver, add all the bluetooth devices you want. Then reinstall the ps3 driver. All devices work. If you want to add more bt devices, remove the ps3 driver again, add more devices, then reinstall the ps3 driver. I have been using all my bluetooth and ps3 driver together for a couple years now with no issues at all. Including my 8-bitdo fc30 pro.
@soulgriever that driver should probably not be used on Ubuntu etc. You should be able to pair a ps3 controller via the desktop Bluetooth GUI etc. However there are some known issues with ps3 and sdl2 which are not resolved on x86 - we have a custom sdl2 for the RPI, but it's not yet available for x86 etc.
