3rd Party Bluetooth Binding. Beta testers needed

My BT adapter is not detected by OH. It is working fine from the cli.

Bus 001 Device 004: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

In the logs I see only this:

Protocol is unknown. Trying to find factory amongst discovered adapters: /9A:CA:AB:7B

I also have problems with the official BT binding, as described here.

I think my dongle is the issue, but I have no clue what to do. Does anyone have a suggestion for me?
