Bluetooth не работает в Ubuntu 15.04

Я установил Ubuntu 15.04 на ноутбук DELL XPS 13 (модель 9343, BIOS A03). Мое внутреннее устройство Bluetooth определяется с помощью hci, значок находится на панели задач, но при сканировании устройств Bluetooth он ничего не находит и сам не может быть найден. Я прилагаю некоторую информацию. Предложения приветствуются.
