After messing with this for a bit I realized I could in fact pass the specific USB bluetooth device as yayitazale attempted above.  The key was to pass it as a path.  Instead of doing  --device='/dev/bus/usb/001/006' Pass that device as a path with read/write access and make the container privileged.  So under your docker container settings, add a path and enter the device path into both the host and container path values and make it read/write: More specific to the home assis
