One precision:  I can't use Bluetooth with Linux, except when I start
the computer on Windows and I reboot into Linux. In this case, bluetooth
works as excepted until I suspend my computer. After resume, Bluetooth
doesn't work anymore.

My computer is an Acer Aspire V3-371-31KW.

Title:
  [Atheros AR9462] Bluetooth looks activated but cannot be used

Status in bluez package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 14.10

  System Information
  	Manufacturer: Acer
  	Product Name: Aspire VN7-591G
  	Version: V1.08
  	SKU Number: Aspire VN7-591G_091B_1.08
  	Family: Sharkbay System

  lspci
  07:00.0 Network controller: Qualcomm Atheros AR9462 Wireless Network Adapter (rev 01)

  
  lsusb -v
  Bus 003 Device 006: ID 04ca:300d Lite-On Technology Corp. 

  
  Steps to reproduce:
  1. Activate a Bluetooth device (for instance a mouse or a nearby device)
  2. On the laptop, press the Bluetooth icon, then "Set Up new Device…"

  Expected result:
  2. A list of available bluetooth devices is shown

  Actual result:
  2. Nothing shows up and the spinning icon keeps spinning with "Searching for devices..."

  It looks like the bluetooth device does not work at all.

  Apparently, there have been previous bugs reported and corrected [1],
  but the situation still occurs with this module on my laptop...
