Hi, I've made my first steps with Proxmox today and ran into an issue with passing my Bluetooth to a VM.

Executing bluetoothctl on the host answers as expected with the controller and I can scan for devices. So I guess it is working properly.
Code: 
root@pve:~# bluetoothctl
Agent registered
[CHG] Controller 3C:6A:A7:21:28:79 Pairable: yes
[bluetooth]#

To see where my internal Bluetooth adapter is connected, I've checked hciconfig -a. Result, it is a USB device.
Code: 
root@pve:~# hciconfig -a
hci0:    Type: Primary  Bus: USB
         BD Address: 3C:6A:A7:21:28:79  ACL MTU: 1021:4  SCO MTU: 96:6

As mentioned in another thread, I've also checked lsusb to see the vendor and device id.
Code: 
root@pve:~# lsusb
Bus 002 Device 005: ID 152d:0578 JMicron Technology Corp. / JMicron USA Technology Corp. JMS578 SATA 6Gb/s

Bus 001 Device 002: ID 0bda:5411 Realtek Semiconductor Corp. RTS5411 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I've tried to add the USB Device via the web-interface by using the Vendor/Device ID as well as via command line using qm set 102 -usb0 host=8087:0aaa. After starting the VM, the Bluetooth device is no longer listed when executing lsusb on the host. I assume this is the expected behavior, as the device is now only available inside the VM. Unfortunately, the VM does not recognize the passed Bluetooth adapter. Executing lsusb on the VM gives me nothing I can work with further :(.
Code: 
~ # lsusb

Bus 003 Device 002: ID 0627:0001
Bus 007 Device 001: ID 1d6b:0001

I very appreciate hints and help to get this working :)

Host is a Dell Wyse 5070
Proxmox Version 8.2.4
VM is Home Assistant installed with the guide provided in this thread with the qcow2 image
 
Have you also tested switching between USB2.0 and 3.0?
You can set this in WebUI too.

Did you see some usefull logmessages with journalctl?
 
Thanks for your answer. Unfortunately there is only a check box regarding USB 3.0 which I cannot untick.

Maybe unrelated: Is it normal that I have to reboot the host after I've passed the device to a VM in order to be able to pass it again? Removing the device from the VM doesn't bring it back to the host.

Checking joruncalctl regarding bluetooth without starting the VM, I can see some errors in the output:

When adding the device via webinterface, journalctl shows:
Code: 
Jul 12 17:06:18 pve pvedaemon[1002]: <root@pam> update VM 100: -usb0 host=8087:0aaa

When I start the VM, journalctl shows some errors regarding Bluetooth and USB interfaces which I think are related to passing the Bluetooth adapter:

If it helps, I've attached the complete journalctl output since last boot before starting the VM and handing over the USB device.

Thank you for help :)

After some more research, I found out that this is maybe a hardware related problem, even if the WIFI-Bluetooth card is working properly on the host. Out of curiosity, I've installed the WIFI-Bluetooth card from my laptop in the Wyse 5070, and lo and behold, the passthrough to the virtual machine worked flawlessly.

I will receive an exchange card within this week and will respond if the setup also works with this card.

Nevertheless, a big thank you @fireon for taking the time to help me and for pointing me in the right direction for troubleshooting. I truly appreciate your support and expertise.

No, normaly not. This should work on the fly.

This sounds good :cool:. Nice that you have found the solution. Very good!

I'm curious already...

Please excuse me, I haven't given any feedback for a long time.

After the replaced WiFi card didn't work, the entire computer was exchanged. However, this also didn't solve the problem initially. After countless hours of trial and error, I realized that I had been repeatedly trying to create the VM using a script from tteck or with the provided VM image from Home Assistant.

I then simply tried to install plain Debian, and voila, it worked immediately to pass Bluetooth to the VM. As a second step, I installed Home Assistant Supervised, and I had no problems with this either.

So, if anyone else has encountered Bluetooth forwarding issues with Home Assistant installed via the tteck script or the official qcow2 image, consider trying a manual installation on Debian instead.
