I have this problem since I do a fresh install Ubuntu 14.10 (previously I don't have this problem in 14.04). I tried to follow any instruction available in internet but it doesn't change anything so I have no idea what to do now. Sreenshot

Here is the output of dmesg | grep -i bluetooth:

[   22.521992] Bluetooth: Core ver 2.19
[   22.522014] Bluetooth: HCI device and connection manager initialized
[   22.522022] Bluetooth: HCI socket layer initialized
[   22.522024] Bluetooth: L2CAP socket layer initialized
[   22.522036] Bluetooth: SCO socket layer initialized
[   22.573800] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
[   22.573804] Bluetooth: BNEP filters: protocol multicast
[   22.573812] Bluetooth: BNEP socket layer initialized

Output of lsusb:

Not supported by the Utopic kernel yet, but it can be made to work

sudo apt-get install build-essential linux-headers-generic
wget https://www.dropbox.com/s/uocd0xqaprm4yvi/bluetooth.utopic.tar.gz
tar -zxf bluetooth.utopic.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/
wget https://www.dropbox.com/s/f503f6r686riiow/fw-105b_e065.hcd
sudo cp fw-105b_e065.hcd /lib/firmware/brcm/BCM43142A0-105b-e065.hcd
echo btusb | sudo tee -a /etc/modules && sudo modprobe btusb

Then check dmesg | grep -i firmware to see if there are any firmware errors and post errors

After a kernel update you will need to recompile the module

cd bluetooth
make -C /lib/modules/$(uname -r)/build M=$PWD 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 modprobe -r btusb
sudo modprobe btusb

and bluetooth should work in a new 3.16 series kernel

  • I tried that but bluetooth still disabled and this is the output of dmesg | grep -i firmware:

    [ 0.126121] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored

  • See if it works after a reboot – Jeremy31 Apr 09 '15 at 09:39
  • Okay, but first I'm gonna try to reinstall the system with download update checked tonight and see if it work and I'll try your advise again, I'll update this comment again as soon as possible – Muhammad Fajar Baskhara Apr 10 '15 at 01:35
  • You could always try http://askubuntu.com/questions/599711/bluetooth-on-lenovo-ideapad-s20-30 as the bluetooth device has the same ID – Jeremy31 Apr 10 '15 at 10:26

    Hi @Jeremy31 thanks a lot man, after reinstalling the Ubuntu 14.10 and retry your advise, bluetooth now work. – Muhammad Fajar Baskhara Apr 13 '15 at 01:07
  • I have to do the same as @Jeremy31. Because I tried to change the kernel version following other answer and something did not work right. – Ratata Tata Apr 21 '15 at 00:28
  • @Orlando Leite I updated answer to include info on what to do after a kernel change, as long as it is a 3.16 kernel through the Update Manager – Jeremy31 Apr 21 '15 at 10:05
