Luca, I looked lsusb output of another bug report you've made and it seems that USB device 13d3:3408 of the X751LA should be handled as AR3012:

Since the question did not receive any useful answer, I thought to scale up the issue. In order to be 100% sure, since I made several tests for another problem I have with the touchpad, I reinstalled entirely the whole system, so now I'm running a fresh install of Ubuntu 14.04 on the mentioned notebook. The Notebook is equipped with a Qualcomm Atheros, the wifi is working fine - at least so it appears to me. The bluetooth app is not able to activate the bluetooth. I installed blueman, and through it I could switch on the bluetooth (at least it says it is on); however when I do a search. it cannot detect any remote device. Moreover, although I set the device as visible, it does not show up on other devices scanner. Hcitool seems to detect the local device: $ hcitool dev Devices: hci0 54:27:1E:51:63:DE However it does not detect remote devices: $ sudo hcitool scan Scanning ... $ (this was after I set my phone as discoverable).
