Hi,
I have a problem setting bluetooth dongle in my ha. I’m running debian bullseye with supervised installation. Both ha and debian are fully updated to the latest stable version.
When I reboot my comp I get this error
On system when I run hciconfig -a I get this

I installed dbus-broker and enabled it.
When I run sudo systemctl status dbus-broker I got this
It seems that after reboot bluetooth dongle doesnt work and it’s not recognized in home assistant.
But if I restart dbus-broker my bluetooth dongle is recognized but I get his
I can’t see in the menu configuration for network interfaces.
and I can’t open ssh web terminal because it’s waiting for supervisor to startup.
If I do hciconfig -a I get his
In my opinion something problem might be in the dbus socket and its avability to home assistant. I’m not sure is this a case, its my guess. But if it is I don’t know how to fix it.
Edit:
After checking some things I found out that mdns stoped running after I restarted dbus-broker. I removed avahi-daemon from my system but it didn’t changed anything.

My adapter is recognized by home assistant but I get unsupported system errors. I checked the docs and it says "The Bluetooth adapter must be accessible to D-Bus ". It’s seems to me that it isn’t accessible to dbus on reboot but if I restart dbus it became available but it breaks some things in ha.
Can someone help me out with this?
Ok, I got this working by restarting Network Manager and hassio-supervisor services. But I still got unsuported installation problem.
The problem is obviously related to dbus. When I do in ssh terminal
I can’t believe it. In /etc/systemd/system/hassio-supervisor.service I just added a line like @k96hkh suggested in this thread and just done systemctl daemon-reload and volla.
No dbus errors, system is supported and everything is working.
After whole weekend trying to make my bluetooth adapter work, I think I found a permanent solution for it. I’m using debian 11 and I reverted all my editing to defaults. I upgraded my kernel to 6.0 from testing branch.
In /etc/apt/sources.list I added
deb http://deb.debian.org/debian/ testing main contrib non-free
deb-src http://deb.debian.org/debian/ testing main contrib non-free
and upgraded my kernel. Bluetooth adapter is recognized on boot and I don’t see any errors or problems for know.
I hope this is the end of the road for me and my adapter.
