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

Hello !

The patch in comment #7 seems to consider my bluetooth adapter as a AR3012 ship.
According to  https://wireless.wiki.kernel.org/en/users/drivers/ath3k, it seems to be a AR3011 ship:

    How to tell AR3011 and AR3012

    You can use lsusb -v to check the device descriptor. If it's AR3011,
the iProduct value is 0. If it's AR3012 the iProduct value is 2.

The iProduct of by device seems to be 0, so my device seems to be a
AR3011 ship.

According to the same page, if I got it correct, the firmware to use for
AR3011 is ath3k-1.fw, not AthrBT_*.dfu and ramps_0x*_40.dfu.

Do you know how to tell ath3k to consider my device as a AR3011 ship?

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

Status in bluez package in Ubuntu:
  In Progress

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...
