Bluetooth BCM43142 человечности 14.04 никакое исследование (tx тайм-аут)
я просматривал много сообщений относительно проблемы, хотя я не мог найти монолитный ответ.
проблема: неспособный к discover\detect другие узлы Bluetooth.

как Вы видите в отрывке выше на последних двух строках - кажется, что существует проблема с драйвером.
обратите внимание, что мы говорим о комбинации-nic. т.е. это - Wi-Fi и bluetooth-устройства на карте физического сетевого интерфейса.
может тот проливать свет на проблему:
- что не так?
- есть ли какой-либо программный продукт? (я знаю, что могу купить другие аппаратные средства),
ОБНОВЛЕНИЕ: я перешел по ссылке pilot6 и сделал изображенные шаги там для обеих архитектуры. т.е. 32 бита и 64 бита, которые я имею, завершают работу компьютера, но вопрос был все же решен. включенный больше информации, если информация необходима, сообщило мне.

я не уверен, хотя кажется, что встроенное микропрограммное обеспечение не было загружено:

см. 4 строки от нижней части- Driver=btusb. таким образом я не уверен, что копирование встроенного микропрограммного обеспечения помогло в так или иначе.
ОБНОВЛЕНИЕ 2: это точно, что я сделал:

Необходимо будет установить встроенное микропрограммное обеспечение сначала. Это может быть сделано с помощью этот ответ .
, Но похоже, что ядро 3.13.0-59 имеет много ошибок. Среди них неспособность загрузить встроенное микропрограммное обеспечение.
я предлагаю обновить ядро до 3,19. Это может быть сделано путем выполнения в терминале
sudo apt-get install linux-generic-lts-vivid
и перезагрузке.
