No unconfigured Bluetooth adapters, but no adapter is working

Installation
1

I have HA running on a Docker container, a BT dongle connected to my PC, and followed all the official docs to set up bluetooth: added bluetooth: to my config yaml, installed and set up dbus-broker, added dbus to my HA container volumes, and running BlueZ 5.64. hciconfig shows my BT dongle up and running.

Every time I try to add “Bluetooth” integration, I instantaneously get this message:

Obviously there is no bluetooth device added nor any pairing process or whatsoever.

Any clue what I could be doing wrong?

2

Bluetooth and Linux are terrible

3

I could have imagined that. Any clue how could I fix this?

4

I haven’t solved this problem yet.

5

Anyone else, any idea?

In general, it turned out to be fixed. Only I didn’t understand how. I completely reinstalled Linux with the inserted USB adapter ORICO BTA-409 (CSR8510A10). While it works, sometimes there are failures, but this is rare and possible due to the large number of Wi-Fi devices. It remains to somehow connect the Bluetooth speaker to the Home Assistant
