issue with bluetooth

[ioannispelelis]

Describe the bug
Bluetooth dongle fails after a few minutes after boot.
When I boot the VM and HA starts bluetooth communication works for a few minutes
Then every bluetooth device is out of order
I have logs in the console that a file in /sys/kernel/debug/bluetooth/hci0 already exists
Only solution to fix the issue is:

• either to reboot the whole VM
• unplug the USB Bluetooth dongle for a few seconds (it clears the files under /sys/kernel/debug/bluetooth/hci0 ) then replug it and go to the HA integrations and reload the bluetooth integration
  It will then work for a few minutes and fail again...

To Reproduce
Steps to reproduce the behavior:

1. Boot the HAFBX VM with A Bluetooth USB dongle plugged in and trasnfered to the VM
2. Wait a few minutes
3. all bluetooth devices appear offline
   

Expected behavior
Bluetooth USB dongle should be stable

Here is the error under HA when it happens:
