Jukka,

For the moment : assuming you have the same harware as me as far as
Bluetooth is concerned (we both have a Acer Aspire V3-371).

The right firmware files for this chipset have normally been found
(thanks arty). However, unfortunately, they won't be included in Ubuntu
for the moment for licensing issues.

A patch exists to make the driver recognise the chipset and was included
in upstream kernel (version 4.2). It probably won't reach Ubuntu until
next release.

Here are some commands to be entered in a terminal to work around the
issue. They should download and install the right firrmware files for
your Bluetooth chipset and a patched driver which recognises your
chipset.

sudo dpkg -i ar9462-dkms_1.5.1_all.deb
sudo apt-get -f install

You might need to reboot. Please tell us if that works.

  (please read)

  I can't use Bluetooth with my AR9462 WLAN/BT-Combo.
  In the link above, it has been fixed, but not for my Adapter ID/Firmware:

  System:
  Ubuntu 14.10 utopic 64bit - 3.16.0-24-generic x86_64

  lspci -nnk
  02:00.0 Network controller [0280]: Qualcomm Atheros AR9462
  Wireless Network Adapter [168c:0034] (rev 01)
   Subsystem: Lite-On Communications Inc Device [11ad:0802]
   Kernel driver in use: ath9k

  lsusb (identified Bluetooth Device)
  Bus 002 Device 003: ID 04ca:300d Lite-On Technology Corp.

  ath9k.conf
  options ath9k btcoex_enable=1

  The "04ca:300d" ID is not in the Kernel, so i added it via dkms.

  I took ath3k.c and btusb.c out of the 3.16.0-24-generic source files
  and changed them:

  (DKMS package in the same style/versioning as in the bug report above)

  dkms status

  Now the new output:

  My patch works, but just like in the bug report above, a Firmware file is missing:
  AthrBT_0x11020100.dfu

  I found it neither in linux-firmware (http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/ar3k)
  nor elsewhere.
