Eu tenho um problema com o bluetooth em um Lenovo G50-70 executando o 14.04 com o kernel 3.16
Pode ligar e desligar o bluetooth a partir da bandeja do sistema, mas parece não ativar o dispositivo real.
Eu instalei drivers com
sudo apt-get install bluez bluez-alsa bluez-audio bluez-btsco bluez-compat bluez-cups \
bluez-dbg bluez-gstreamer bluez-pcmcia-suporte bluez-ferramentas bluez-utils python-bluez \ bluewho indicador-bluetooth libbluetooth-dev libgnome-bluetooth11 libbluetooth3 \ python-gobject python-dbus
e reiniciado, mas não fez diferença. rfkill não mostra nenhum bloqueio duro ou suave.

Nada disso parece um dispositivo bluetooth para mim.
O dmesg parece sugerir que não há firmware
dmesg | grep -i Blue

outras pessoas com problemas semelhantes tiveram uma mensagem de erro como
[ 2.237027] Bluetooth: Firmware file "ath3k-1.fw" not found
mas eu não recebo nada assim.
Eu tentei reinstalar o firmware linx sem alterações.
Alguma outra sugestão?
Obrigado Garrett
