Bluetooth won't detect devices 14.10

Question

I have a Gateway NE-5224u. When I try to sync it with my bluetooth speakers, it doesn't detect them. Windows and android do. Any ideas? Any commands I should run in order to check how the bluetooth adapter is configured and working?

Thanks in advance!

After running this command

lsusb; hciconfig -a; dmesg | grep -i firmware

I get this result:

Ok,

Actually this should work as there is another fix in the utopic kernel that helps atheros bluetooth

sudo apt-get install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libgl1-mesa-glx-lts-utopic libegl1-mesa-drivers-lts-utopic

Reboot and check uname -a if it isn't at least 3.16.0-32 do sudo apt-get update && sudo apt-get upgrade and reboot

If you wish to keep your current kernel, then

wget https://www.dropbox.com/s/76c9nfyeb01eki6/bluetooth-3.13-48.tar.gz
tar -zxf bluetooth-3.13-48.tar.gz
cd bluetooth
cp /boot/config-$(uname -r) .config
cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers
make -C /lib/modules/$(uname -r)/build M=$PWD modules
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
sudo cp ath3k.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/

Reboot and if you do updates and notice the bluetooth isn't working then

cd bluetooth
make clean
cp /boot/config-$(uname -r) .config
cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers
make -C /lib/modules/$(uname -r)/build M=$PWD modules
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
sudo cp ath3k.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/

And reboot.

If you notice that bluetooth isn't working after a cold start about 1/3 of the time, I would upgrade to the Utopic 3.13.0-32 or higher kernel as the fix is in there

EDIT: Found out why original answer didn't work as intended

sudo apt-get install build-essential linux-headers-generic git linux-firmware
git clone https://github.com/jeremyb31/bluetooth-3.13.0-37.git
cd bluetooth-3.13.0-37/bluetooth
cp /boot/config-$(uname -r) .config
cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers
make -C /lib/modules/$(uname -r)/build M=$PWD modules
sudo modprobe -r btusb && sudo cp *.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
echo btusb | sudo tee -a /etc/modules
echo ath3k | sudo tee -a /etc/modules

Originally had cd bluetooth-3.13.0-37 and it needed to be cd bluetooth-3.13.0-37/bluetooth

Second edit: Now that you can discover devices you likely just need

pactl load-module module-bluetooth-discover

You may have to unpair and redo the pairing sequence to get the audio to work
