Generic PS3 Controller no longer work in Recalbox 7.0.1 on RPi4
I have a RPi3 with Recalbox 6.1 and I recently bought a RPi4 to install 7.0.1 on it and use the RPi3 for other things. I have a generic PS3 controller and, although it never worked with bluetooth, It always worked perfectly using an usb cable on the RPi3. I did a fresh install of Recalbox 7.0.1 in the RPi4 and copied my roms, but now, my PS3 controller is not recognized, even using usb cable. I looked at recalbox config file and the PS3 controller option is enabled. Also, I tried the three driver options (bluez, official and Shanwan), but none of them worked. After several tests, I've discovered that the problem only occurs in RPi4, because I downloaded the RPi3 version of Recalbox 7.0.1, and I did a fresh install on another micro sd and tested on RPi3, and the controller was detected automatically and it works without problem. So, apparently the RPi4 version of Recalbox is missing some driver or file. I created a thread in Recalbox Forum with this issue (Link Here), and I got help from @zing who gave me some indications to do some tests, but it wasn't possible to get a workaround, so he asked me to post the issue here. Please let me know if you need any additional info.
