Bluetooth not working on Asus X751LA

I'm running a fresh install of Ubuntu 14.04.
The Notebook is equipped with a Qualcomm Atheros, the wifi is working fine, while the bluetooth does not find any device, and does not send any signal, although the icon on the panel is active.

Below are the dump of relevant commands:

$ lspci -v

Any help would really be appreciated.
