I'm getting this error message on reboot "failed to open vchiq device"

Hi!

First post on this forum.

So I built my first emulationstation with Raspberry Pi 3 and RetroPie. Everything went well until I started to mess around with the Pi's bluetooth configurations. For some reason I could't get my ps3 controllers to work via bluetooth so I started to investigate. I installed bluez, other drivers and firmware through terminal. I even installed ps3 controller drivers with retropie setup, but it didnt help.

After some frustration I just started to install just about anything to get the controllers working. At this point my RetroPie won't start when rebooting. Instead I get an error message that says "failed to open vchiq device".

Any help at this point would be appreciated. I'm considering re-installing RetroPie from scratch.

Thank you :)

Did you try first using the sixad driver? I don't think the controller works as a generic bluetooth device. Are the controllers the only bluetooth devices you are using?

I would 1) re-install from scratch, 2) pair any other bluetooth devices you want to use, 3) install sixad from retropie-setup.

After that, simply plugging in the controller once should register it with bluetooth. You never have to actually pair it yourself. After the initial plug-in, hitting the PS button should pair it up, and from there Emulationstation should detect it with no issues.

I'm only suggesting #1 (reinstalling) because I haven't a clue what that message means, and not knowing what you tried, it's probably easier to re-install than attempt to backtrack. #2 is necessary because sixad disables something that bluetoothctl needs (some kernel module I think, I forget), and you won't be able to pair new devices after that.

Once you get this working, before you tinker with anything else, I'd highly recommend saving an image of your card, so that the worst-case scenario is simply backtracking to a working system, not a brand-new installation.
