Estou executando o Ubuntu 16.04 LTS no meu laptop MSI GS70 2QD com o kernel 4.13.0-32-genérico.
O problema que estou tendo é que meu computador tem recursos de bluetooth, mas o kernel não é capaz de encontrar os drivers bluetooth.
Quando executo rfkill list , a saída é:
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
quando executo lsusb , a saída é:

Eu li muitos artigos diferentes sobre esse problema exato com o driver AR3012, mas não consigo obter nenhuma das maneiras diferentes de trabalhar, então ou eu estou fazendo algo errado, ou eu não estou entendendo completamente o que eu deveria fazer.
Se houver mais alguma informação de que você precise para me ajudar, por favor me avise.

Esse problema foi causado por Atheros usando o mesmo ID para dois dispositivos Bluetooth diferentes, semelhante ao link Eu atualizei o código fonte do 4.13 para o seu dispositivo bluetooth, no terminal
sudo apt-get install git dkms build-essential
git clone https://github.com/jeremyb31/bluetooth-4.13-ath3004-rome.git
sudo dkms add ./bluetooth-4.13-ath3004-rome
sudo dkms install bluetooth-3004/0.1 Edite também echo "blacklist ath3k" | sudo tee -a /etc/modprobe.d/blacklist.conf
