Bluetooth adapter not recognized

I am starting with BBB. I bought a Bluetooth USB dongle: Bluegiga BLE112 adapter

Unfortunately (even after a reboot) when I type the hciconfig command I do only see a blank line.

Typing “lsusb” shows the device.

I did try some generical tutorials on the net but no success until now.

Can somebody could point me a tutorial with BBB and Angrstrom distribution to debug a Bluetooh device ?
I suspect that not the right module are loaded from the kernel but I am not sure.

Thank you
