Shame on me.
I was using the mini-USB cable instead of the DS Jack cable. Coming from RPi I tought was the same.
Now it's working perfectly.
In the meantime, I burned the Vanilla image, but no NAND support, and I see that also audio devices are also limited to USB and analog.
I would like to use it as Domoticz server and also with Kodi attached via HDMI. I will test the Vanilla and in case I will go back to legacy.
