Hi again,
I tried all the time with a Rasberry pi 2b, and as The Pi Hut USB Wi-Fi Adapter. With no success. I have also a raspberry pi zero w, and in this board this method was working.
I assume that there is something in the layout of the system that doesn’t enable the wifi usb sticks on the Raspberry pi 2b.
at the end a went with this method forward: Guide: Connecting Pi with Home Assistant OS to wifi (or other networking changes)
