@Jeremy and @Joseph
I'm commenting here (and to 1394368) to conclude the discussion should anyone else be fighting with the same issue.

As Jeremy suggested I copied both these files from Windows' (Program Files\Common Files\QCA-Bluetooth) to  Ubuntu's /lib/firmware/ar3k -folder: 
- AthrBT_0x11020100.dfu
- ramps_0x11020100_40.dfu

Now there are no more errors on the dmesg and Bluetooth is working on both of these experimental kernels:
- 3.18.0-14-generic #15 SMP Fri Feb 27 18:38:10 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
- 4.0.0-040000rc1-generic #201502261652 SMP Thu Feb 26 16:56:29 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Bluetooth still does not work on published kernels: 
- 3.16.0-31-generic #41~lp1352821v1 SMP Fri Feb 20 20:52:34 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux OR 
- 3.16.0-30-generic #40-Ubuntu SMP Mon Jan 12 22:06:37 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Even though Bluetooth now works, at least bluetooth mouse doesn't
automatically reconnect after restart. Instead mouse text "flickers" in
Bluetooth GUI screen. After clicking "ON" button (on bluetooth gui) for
several time the bluetooth mouse might reconnect - or not.

  devices

  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1352821

  
  Bluetooth on Ubuntu 14.10 running on Acer Aspire V3-371-79RJ laptop does not work. WiFi on the same device works normally and also bluetooth seems to work normally, but when searching for external devices Ubuntu cannot see any bluetooth devices.
   
  I've tried to connect to both bluetooth mouse and an Android phone, no luck. On another Ubuntu laptop the same external bluetooth devices are visible and work ok.

  lspci -nnk printout includes this:
  02:00.0 Network controller [0280]: Qualcomm Atheros AR9462 Wireless Network Adapter [168c:0034] (rev 01)
   Subsystem: Foxconn International, Inc. Device [105b:e07d]
   Kernel driver in use: ath9k

  and lsusb printout includes this:
  Bus 002 Device 002: ID 0489:e076 Foxconn / Hon Hai

  Full listings are attached.

  
  What was expected to happen:
  - Expected that Ubuntu would find my bluetooth mouse and phone when searching for new bluetooth devices.

  What happened instead:
  - Everything seemed to work ok, but nothing happened. Ubuntu does not see any bluetooth devices.
