I'm tested Kubuntu 14.04 x64 with 3.11.10-03111008-generic, 3.13.0-24-generic, 3.15.0-031500rc2-lowlatency kernels now. And now stay on 3.15rc2.
Nothing changes. I think this is not kernel's problem. May be my BT device do not recognized because upstart-udev and systemd-udev psrts conflicts. How do you think?

Now I have this logs:
dmesg | grep -i blue
[    5.530076] Bluetooth: Core ver 2.19
[    5.530119] Bluetooth: HCI device and connection manager initialized
[    5.530129] Bluetooth: HCI socket layer initialized
[    5.530133] Bluetooth: L2CAP socket layer initialized

[    5.568256] Bluetooth: RFCOMM socket layer initialized
[    5.568265] Bluetooth: RFCOMM ver 1.11
And I can see nothing about device...(((

In 13.10 I must manualy use btusb(if it do not loaded after resume) module to work BT. Now this module do not used by default:
#lsmod | grep blue
bluetooth             465597  10 bnep,rfcomm
6lowpan_iphc           18968  1 bluetooth
# modprobe btusb
# lsmod | grep blue
bluetooth             465597  11 bnep,btusb,rfcomm
6lowpan_iphc           18968  1 bluetooth

But after manual module loading nothing changes...(((

Title:
  Has issues with bluetooth

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have Qualcomm Atheros AR9485 Wireless Network Adapter [168c:0032]
  (rev 01) on Acer TM B113-E notebook.

  When I use ath9k with 3.11 kernel then all works fine. WiFi and Bluetooth works as well.
  I have problem with bluetooth when install some later kernels(I'm test 3.15rc1 and (3.13 or 3.14)) from http://kernel.ubuntu.com/~kernel-ppa/mainline/
  After this installation I have not bluetooth device! When I switch Wi-Fi by acpi key, I can switch only Wi-Fi to on or off state(I saw status by "rfkill list"). Bluetooth device will not reconize for me...
  But if I will power off  notebook and disconnect battery, then after power on I'm get working Bluetooth.

  I could not pay attention to this troubles but now we have Ubuntu 14.04(I tested on Kubuntu 14.04).
  After installed Kubuntu 14.04 I have working only Wi-Fi. Power off+disconnect battery and other probes(such as I probe to install non-free firmware) do not have results. System do not recognize BT device... I can not see this device in rfkill list and in KDE's System Settings->Bluetooth...
  In 3.11 kernel and later kernel I have problem with bluetooth after sleeping too. Module do not start after resume. I wrote script with manual starting of btusb module and get working BT after resume.
