I am using ubuntu latest lts (14.04.3). My laptop does have Bluetooth and I can use it in windows 8. However in Ubuntu it seems that the OS doesn't recognize the hardware.It is not listed on the top bar, under the Hardware>Bluetooth.

    It might help if you can tell us "how do you know" it isn't working? What are the signs of your problem? – Sepero Oct 29 '15 at 12:33
  • Please edit your question and add output of lspci -knn | grep Net -A2; lsusb terminal command. – Pilot6 Oct 29 '15 at 20:22
  • it's not showing in the top bar. and it's not listed under all setting>hardware>bluetooth – Mahanmeh Oct 30 '15 at 15:44
  • Please reconsider the question I have edited the text. – Mahanmeh Nov 02 '15 at 05:51
  • Are you sure you did not miss anything in lsusb. – Pilot6 Nov 02 '15 at 12:35
  • This wireless/bluetooth chip is not supported by Linux yet. – Pilot6 Nov 02 '15 at 17:59
  • I had the problem with the wireless. I posted here and now it's solved and I amusing the wifi right now. http://askubuntu.com/questions/678145/my-wifi-qualcomm-atheros-device-168c0041-rev-20-doesnt-show-up-and-work-in isn't there any way to get the bluetooth work as well? – Mahanmeh Nov 02 '15 at 18:15
  • But you can see in that answer that there must be 0cf3:e300 Atheros Communications, Inc. in btusb. – Pilot6 Nov 02 '15 at 21:45
  • It looks like that driver disabled bluetooth by some way. Try to install kernel 4.3. There is native support ow your wireless adapter. And probably bluetooth will work too. – Pilot6 Nov 02 '15 at 21:48

Your wireless/bluetooth adapter is natively supported by kernel 4.3.

The backport you have installed to get your wireless adapter working probably has broken the bluetooth.

Install the kernel this way:

mkdir ~/linux-4.3
cd ~/linux-4.3
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-wily/linux-headers-4.3.0-040300-generic_4.3.0-040300.201511020949_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-wily/linux-image-4.3.0-040300-generic_4.3.0-040300.201511020949_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.3-wily/linux-headers-4.3.0-040300_4.3.0-040300.201511020949_all.deb
sudo dpkg -i *.deb

and reboot.

You will also need an updated firmware. It has been uploaded to proposed already. Install the deb file this way:

wget https://launchpad.net/ubuntu/+archive/primary/+files/linux-firmware_1.127.18_all.deb
sudo dpkg -i linux-firmware_1.127.18_all.deb

This package will get into main repositories in a week or too.
