I'm trying to sync my laptop with my bluetooth headphones. The thing is that Ubuntu doesn't detect any device at all.

I've googled a little, tried some possible solutions. Like theese:

Bluetooth not working in ubuntu 14.04 LTS Ubuntu 13.10 bluetooth is not working

But still not detecting any device.

Any ideas?

lsusb && lspci -nnk | grep -iA2

returns...

    Please add the info, because after the next power cycle it might not work due to a bug. It isn't going to harm your hardware but it might make you pull your hair out – Jeremy31 Jan 15 '15 at 23:42

Since the bluetooth adapter is an Atheros AR3012 it might suffer from a bug that will cause it to sometimes fail to load firmware during a cold boot. A workaround that has worked for me is to blacklist ath3k with echo "blacklist ath3k" | sudo tee /etc/modprobe.d/ath3k.conf and then you can use terminal after booting to load ath3k with sudo modprobe ath3k or you can gksudo gedit /etc/rc.local and add modprobe ath3k above the last line that has to be exit 0, save, exit gedit, and reboot
