HA does not detect Sonoff ZBDongle-P
I'm sure this is something simple I'm missing but:
I purchased a SONOFF Zigbee 3.0 USB Dongle Plus. I have Home Assistant installed on a Raspberry Pi 4 Model B. HA does not detect the dongle at all. Not when the dongle is plugged directly into a USB 2.0 or USB 3.0 port or into a known working powered USB hub which is plugged into a USB 2.0 or USB 3.0 port.
Nothing makes HA see it. It is not listed under Integrations or System Hardware. If I run dmesg on a terminal it does not appear (though the hub does).
What am I missing? Any other info needed?
