Best Answer

This adapter is not supported by Ubuntu kernel yet. It will be supported in newer kernels, but I build a dkms module for kernel 4.2. I suggest to do the following:

  1. Install kernel 4.2 by running:

    sudo apt-get install linux-generic-lts-wily

and reboot.

  1. Install the btusb module:

    wget https://launchpad.net/~hanipouspilot/+archive/ubuntu/bluetooth/+files/btusb-bcm105b-dkms_0.1_all.deb
sudo dpkg -i btusb-bcm105b-dkms_0.1_all.deb

  2. Convert and install firmware using this answer.

For kernel 4.2 probably you will need to rename the file to BCM.hcd.

  1. Reboot and test bluetooth.
