Player X USB doesn't recognize in rpi4

Hi,
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.

Hi
I have the same issue. I have to re-power by player X board before it is seen.
Did you ever find a solution for this ?
Cheers
