[Bug 1397885] [NEW] [Atheros AR9462] Bluetooth looks activated but cannot be used

[Pierre Equoy]

Public bug reported:

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...
