After installing the package with new firmware files:

Output of  "dmesg | egrep 'ath3|ar3|Bluet'":

Title:
  Bluetooth with AR9462 doesn't work (New ID /Firmware)

Status in linux-firmware package in Ubuntu:
  Incomplete

Bug description:
  This is (kind of) a duplicate of:
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1024884
  (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
  ar9462, 1.5.1, 3.16.0-24-generic, x86_64: installed

  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.
