Hello!
I wanted to share my experience with using a Bluetooth device.
The Device I used was the ZEXMTE Z01 Dual Antenna Adapter
My Setup is a bit Complex, so I was Happy with the Plug And Play for the Most part
TrueNas Scale (Root Server) → Passthrough USB to VM → Passthrough to Docker
On my Ubuntu 20.04 VM, the drivers loaded automatically.

[ 1236.965452] Bluetooth: BNEP filters: protocol multicast
[ 1236.965460] Bluetooth: BNEP socket layer initialized
The only configuration on my VM I had to do was run
sudo apt-get install bluez*
I hope this can help someone who needs a Bluetooth device!
