RBPI3B+ BLE 4.0 USB Dongle question

[Stefan Parvu]

Hi,

Im trying to see if I can make this device [1] work with FreeBSD 12 RELEASE. This is a 
CSR8510 [2] based bluetooth usb dongle, which I understood should be supported in FreeBSD
12. Is this right ? 

When Im trying to use this device I see the following:

dmesg

ubt0 on uhub1

  Name: ngctl1117       Type: socket          ID: 00000015   Num hooks: 0

I cannot start the service, something most likely wrong: driver, not properly configured.

root at k1iot:~ # service bluetooth start ubt0
/etc/rc.d/bluetooth: ERROR: Unable to setup Bluetooth stack for device ubt0

Anyone any ideas ? Thanks.
