After following through several other Articles about seemingly the same problem I failed repeatedly to pair Bluetooth devices with my Laptop Acer E5-571. The GUI shows Bluetooth tools, but searching for devices, switched to visible, gives no results. Some config information:

lsusb outputs:

Since you figured out how to upgrade to a 3.18 kernel, upgrading to 3.19.1 will fix your issue as will the 3.16.0-32 that 14.10 should be able to install with the update manager

Atheros bluetooth does need firmware sudo apt-get install linux-firmware

  • Upgrading to 3.19.1 did the trick indeed. Thank you very much.
