Troubleshooting • Re: Problems with USB-devices (SSDs)

Hi,
No, it's not powered. So you think the problem is probably the power? I do have a powered hub, but when I tried that in the past, i got a message that the Raspberry was OVERpowered... I tried the USB-port of my router and a powerbank. I cannot regulate the power of those devices (and powerbanks often shut down if not enough power is drawn, so that could be problematic if the Pi isn't used).

From having read elsewhere on the forum:

The total current drawn from the four USB ports on Raspberry Pi 5 is limited by default to a nominal 600mA; this limit is automatically increased to a nominal 1.6A when the USB-C PD Power Supply is detected.

So if your devices (sometimes) need more than that then something will fail.
If your current hub is of good quality then it should not back feed power to the Pi and you should be able to power it with a separate power supply. That's the best thing I can advise to try.

Is there a way to discover if the power consumption is the problem? Some log where I could find that?

You could look at all the specs of your devices and add up their maximum rated power.

i don't know what devices this are:

Code:

Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub  bcdUSB               2.10Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hubDevice Descriptor:  bcdUSB               2.00

The last one is the onboard-hub from raspberry pi itself, I guess?

I think both are the onboard hubs.

Maybe it's important I connect the raspberry with a UTP-cable to my router?

I don't think that matters.
