Сенсорная панель Волшебства Apple 1 - 'прекращает работать' каждые несколько минут

Я только что купил Сенсорную панель Волшебства Apple 1 и подключил ее к моей Ubuntu 15.10 (теперь 16.04) система. Это все работало безупречно.

После того, как соединенный, сенсорная панель 'прекращает работать' каждые несколько минут. Я не знаю, становится ли это разъединенным от Bluetooth или выключает себя. Все, что я знаю, - то, что я могу получить его работающий снова путем нажатия кнопки питания на сенсорной панели. Иногда я должен сделать это дважды или даже три раза, но затем это будет работать снова.

Я попробовал обычные вещи как изменение батарей, удаление его от Bluetooth и добавления его снова. перезагрузка моей системы и передобавление его.

Если я оставлю устройство подключенным в течение ночи, когда я возвращусь к нему утром, касание сенсорной панели разбудит систему.

У меня была та же проблема на Ubuntu 18. Вывод вашей строки выглядит примерно так, как я видел на моей машине. Я исправил свою проблему, отключив автоматическую приостановку USB .

Я позволял модулю ядра обрабатывать HIDP (я думаю, вы можете проверить это, перейдя к /etc/bluetooth/input.conf и проверив, что UserspaceHID не установлен на true), и по умолчанию ядро ​​автоматически приостановит работу USB-устройств. не используется для экономии энергии. И, видимо, такое поведение вызывало хаос в моем волшебном трекпаде.

Такое поведение, похоже, проявилось в выходных данных sudo btmon. Я мог видеть, как HCI посылает команду на выход из режима сниффинга (он же режим энергосбережения?). Иногда он успешно завершается, переходя в активный режим и повторно соединяясь с трекпадом. Иногда этого не происходит, и я вижу: 

> HCI Event: Mode Change (0x14) plen 6                                                                                                                               #10952 [hci0] 807.142497
        Status: Connection Timeout (0x08)
        Handle: 256
        Mode: Active (0x00)
        Interval: 0.000 msec (0x0000)

И тогда трекпад перестает работать, пока соединение восстанавливается. После отключения usb auto-suspend он всегда остается в активном режиме, избегая проблем, вызванных входом / выходом из режима прослушивания.

Одна вещь, которую пропускает статья из архива вики, это как найти правильное устройство bluetooth в выходных данных lsusb. Возможно, это было очевидно для некоторых, но не для меня. Поэтому обязательно запустите lsusb -v или используйте usb-devices для получения более подробной информации, которая облегчит идентификацию нужного устройства.

Я знаю, что этот вопрос старый, и я свободно признаю, что не полностью понимаю все элементы этой проблемы, но, надеюсь, кто-то найдет этот ответ полезным.

Это может помочь исследовать вывод journalctl -u bluetooth.service

, у меня были проблемы с модулем Bluetooth в моей Lenovo Thinkpad Yoga (работающий 15.10-> 16.04) соединяющийся с моим динамиком Цвета Bose Soundlink после пробуждения от, приостанавливают, а также некоторые другие проблемы как отложенное и отброшенное аудио. Я взял адаптер Bluetooth usb , который поддерживал еще некоторые наборы функций, которые были включены в Bluetooth, так как мой ноутбук был произведен, и он работает вполне хорошо. Связь Bluetooth между адаптером и динамиком, и Ubuntu рассматривает его как USB-устройство.

    Это может зависеть от драйверов сенсорной панели - возможно, Ubuntu doesn' t поддерживают эту опцию на ThinkPad. Вы могли проверить настройки BIOS? I' ve замеченные опции как это в BIOS прежде. – seanlano 15 August 2017 в 15:40
