I am using the latest Retropie in Raspberry pi 4 4GB.
When I update the Bootloader, it does not recognize PlayerX after rebooting the unit.
Both P1 and P2 do not respond to any buttons or keys, but the Welcome screen says 2 Gamepads Detected.
If I plug and unplug the USB cable once, it will be recognized, but after rebooting, it will not respond.
I can use the bootloader up to 2020/07/16 without any problem, but newer versions will not be recognized.
I would like to know if there is a solution.
