Hi Mathias,
Sure, here are the commands input and dmesg output:

I'm not sure. I found that PM Kconfig is enabled, but the errors also occur
if it's disabled, too. I didn't find any PM runtime configuration.

Here I tried the current kernel configuration with enabled PM:
user@...t:~# for i in $(seq 1 6); do echo on > /sys/bus/usb/devices/usb${i}/power/control; done

After inserting the USB flash drive, nothing happened. I'll try to disable
the PM completely and repeat the experiment. Until then I hope the logs
above can help to analyze the problem.
