I have strange behaviour on RPi4
I need to connect my pi to wifi.
But it is not possible to connect while it is booted from SSD
This is what I find in log

When I boot from SD card wifi sonnect without problem.
Issue is, USB ports of an RPI are not designed to power SSD or HDD. They are limited on the power they could provide. It’s technical limitation on the SBC. We always recommend to use a dedicate PSU on attached SSD/HDD.
