@Daryl yes, i confirm, i use this controller with USB 2.4 Ghz dongle.
I tried to use it in Retropie, there it worked fine.
In Recalbox, when i run run the command cat /dev/input/js0 in the console, it does not show any responds on left and right, other directions and buttons work correctly.

@glook Thanks for the diagrams. Mine came with no papers at all and I followed the joystick orientation from the video (obviously wrong). My wiring was correct, but one joystick was mounted upside down. Knowing the joystick connector is "down" I could see which joystick was mounted wrong. It was strange it was always flipping the last configured joystick. All is working now 🙂
