intel ac 8260 bluetooth, не работающий - Ubuntu 16.04 LTS

Я недавно купил беспроводную карту GC-wb867d-i для своего нового рабочего стола. часть Wi-Fi работает хорошо, однако Bluetooth не woring. Следующее является некоторой диагностической информацией:

$ uname -a:

$ rfkill list all:

$ lsusb; dmesg | egrep -i 'blue|firm':

похоже, что встроенное микропрограммное обеспечение для карты не работает. У кого-либо есть некоторая идея?

Между прочим. У меня действительно есть двойная установка OS на этой машине. win10 и ubuntu 16.04 LTS. Wi-Fi и Bluetooth все хорошо работают под win10.
