These are the soldering s you should check :

See if there are no breakages in them.

If you only connect both your controller and keyboard, without other devices, do they work OK then ?

@BuZz which was my first thought however I installed the original 4.6 that I had on file from way back when.

Don't know too many 3b+ that wont run 1500 with 1-2 overvoltage with a pi4 power supply

for N64 emulation I had this unit running stable all the way up to 1575 with the ice tower so from a hardware point of view doesn't make sense

@the_loaf
I noticed in the script above about
(usb_submit_urb failed with result
I have that problem. When it installing, i guess the emulates, at the end of the scripts on the tv screen
i notice "usb_submit_urb failed with result-2"
what is that and how to fixed that

Thanx @Fiddla01 Fiddla01 for the new threat that brought us a solution.

@mitu that saves me a lot of sleep.

Not perfekt but a way i can live with it

@therealtitleist said in USB Ports not working Retropie 4.7.1 / Raspberry Pi4B:

Does that point to a hardware failure?

Most likely yes.

@lostless said in RPi4 USB ports guide:

@gordonfreemanjr Ignore what the controller is showing on its LED face.

I agree. My bluetooth Wii U Pro clone gamepads also only light the first player LED even if they are working fine for different players in Retropie.

DC 5V A2.

2A is not enough
