Troubleshooting • Re: Overcurrent on Raspberry Pi 5

Okay, you have a 3A power supply which limits USB current to 600mA. Best solution is to get a RPi PSU for Pi5, which is capable of 5A and will negotiate a higher USB current limit.n Alternatively you could try

Set usb_max_current_enable=1 in /boot/firmware/config.txt to enable USB boot.

which will increase the USB current limit, but may crash the whole system if you run out of current overall.

But the overcurrent warning is appearing with no devices plugged in to USB ports.

I've just tried booting a Pi5 8Gbyte with no card, no USB devices and a RPi official 3A PSU. On the diagnostics screen, the end of the power supply line is 'usb_over_current=0' whereas for the OP it is 'usb_over_current=1'. I don't get any of the 'over-current' lines that are in the OP's first photo. (And though I doubt it would make any difference I have not set the 'usb_max_current_enable' to '1''.)

I doubt that using the Pi5 5Amp supply will fix the OP's issue.
