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

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 – Muhammad Fajar Baskhara Apr 9 '15 at 1:50
  • See if it works after a reboot – Jeremy31 Apr 9 '15 at 9:39
  • 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 1:35
  • You could always try askubuntu.com/questions/599711/… as the bluetooth device has the same ID – Jeremy31 Apr 10 '15 at 10:26
