Блютуз не работает на 14.04 с BCM43142

У меня есть Acer Aspire E5-551G. Wi-Fi работает нормально, но Bluetooth не работает?. Я уже пробовал несколько способов решить эту проблему, но у меня ничего не получилось. Вот некоторые выводы, которые потребовались различными подходами к решению моей проблемы.

Первоначально я работал с 3,13, но мой тачпад не работал с этим

После перезагрузки Bluetooth больше не работал. Я узнал, что я должен был добавить btusb в /etc/modules, Но когда я сейчас перезагружаюсь, я получил записи Bluetooth в панели управления Gnome (эта вещь в правом верхнем углу), которая не будет работать и будет перенаправлять меня только на мои настройки сети. После включения Bluetooth в моих настройках появляется вторая Bluetooth-запись, которая работает.
