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

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.
You may well be right, in which case the conclusion will be that the camera accident has damaged the Pi -- almost certainly not repairable (unless you can source a new RP1 chip and replace the original, and even then no guaranteed fix). Cure will then be a new Pi5 -- but with that many USB peripherals, I would certainly recommend an upgrade to the PSU as well.
I already bought the new PSU and I'll see if it works but if it doesn't then I'll buy a new pi.
