Installed kernel v4.4-rc2+cod1-wily, powered machine off, powered on,
checked that the kernel is running, but no visible change,
unfortunately. When turning on my wireless headphone, the little lock
sign in the indicator applet repeatedly turns on briefly and disappears
again. When this happens, no messages in syslog appear. I manage to set
up the bluetooth connection by "Connection" setting the slider to "on"
in the right moment after turning the headphone on, but this is a matter
of luck. Below syslog messages while I do these things, and then finally
turn my headphone off. There are a couple of error messages that might
be of use.

Title:
  btusb.ko preferred over ath3k.ko for Atheros  AR3012 Bluetooth 4.0

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Since upgrading from 14.10 to 15.04 and then 15.10, my Bluetooth is
  buggy (e.g., it does not automatically connect to my headphone, needs
  manual "turning on" in the indicator applet and some good luck to do
  this).

  My bluetooth device is

  # lsusb | grep Blue
  Bus 004 Device 014: ID 0cf3:3004 Atheros Communications, Inc. AR3012 Bluetooth 4.0

  I think this device should be handled by ath3k.ko:
  # modinfo /lib/modules/$(uname -r)/kernel/drivers/bluetooth/ath3k.ko| grep 3004
  alias:          usb:v0CF3p3004d*dc*dsc*dp*ic*isc*ip*in*
  alias:          usb:v04CAp3004d*dc*dsc*dp*ic*isc*ip*in*

  # uname -r
  4.2.0-18-generic

  Indeed, ath3k.ko is loaded

  # lsmod | grep 'ath3k\|btusb'
  ath3k                  20480  0
  btusb                  45056  0
  btrtl                  16384  1 btusb
  btbcm                  16384  1 btusb
  btintel                16384  1 btusb
  bluetooth             516096  48 bnep,ath3k,btbcm,btrtl,btusb,rfcomm,btintel

  However, if I remove ath3k, bluetooth keeps streaming sound to my headphone:
  # modprobe -r ath3k
  [noting happens]
  while, if I remove the generic module
  # modprobe -r btusb
  the entire bluetooth architechture breaks down, my headphone goes silent, and sound now comes out of the built-in speakers.

  I'd hope that if ath3k was actually used, my bluetooth would be less
  buggy. What can I do?
