Bluetooth не обнаруживает никаких устройств - Dell XPS 13 (16.04) [решено]

Я посмотрел на другие решения и темы для этой проблемы, но ни один из них не работал для меня. Я использую Dell XPS 13 для подключения моих новых наушников Jaybird X3. До сих пор ноутбук не смог обнаружить ни мои наушники, ни мое мобильное устройство.

РЕДАКТИРОВАТЬ: все устройства находятся в режиме обнаружения. Я попытался переустановить Bluetooth, используя этот ответ /questions/511810/bluetooth-v-ubuntu-1604/511814#511814 и он не работал. Я не уверен, почему, но теперь BLueman Assistant говорит: "Адаптеры не найдены".

Я запустил несколько команд в терминале, и вот результаты:

$ sudo service bluetooth status
