Apple Magic Trackpad 1 - "перестает работать" каждые несколько минут

Question

Apple Magic Trackpad 1 - "перестает работать" каждые несколько минут

Я только что купил Apple Magic Trackpad 1 и подключил его к моей системе Ubuntu 15.10 (теперь 16.04). Это все работало без нареканий.

После подключения трекпад "перестает работать" каждые несколько минут. Я не знаю, отключается ли он от Bluetooth или отключается. Все, что я знаю, это то, что я могу заставить его работать снова, нажав кнопку питания на трекпаде. Иногда мне приходится делать это дважды или даже трижды, но тогда это сработает снова.

Я пробовал обычные вещи, такие как замена батарей, удаление его из Bluetooth и добавление его снова. перезагрузка моей системы и повторное добавление.

Если я оставлю устройство подключенным на ночь, когда я вернусь к нему утром, прикосновение к трекпаду разбудит систему.

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

Я позволяю модулю ядра обрабатывать HIDP (думаю, вы можете проверить это, перейдя в /etc/bluetooth/input.conf и проверяя это UserspaceHID не установлен в true), и по умолчанию ядро автоматически приостанавливает использование неиспользуемых USB-устройств для экономии энергии. И, видимо, это поведение вызывало хаос в моем волшебном трекпаде.

Такое поведение, казалось, показало себя в выводе 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 это не так, и я бы увидел:

> HCI Event: Mode Change (0x14) plen 6                                                                                                                               #10952 [hci0] 807.142497

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

Одна вещь, которую пропускает статья из архива вики, это как найти правильное устройство Bluetooth на выходе lsusb, Возможно, это было очевидно для некоторых, но не для меня. Так что не забудьте запустить lsusb -v или использовать usb-devices чтобы получить более подробную информацию, которая облегчит идентификацию устройства, которое вы хотите.

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 изучить вывод journalctl -u bluetooth.service

У меня были проблемы с модулем Bluetooth в Lenovo Thinkpad Yoga (работает 15.10 -> 16.04), подключенным к моему динамику Bose Soundlink Color после пробуждения из режима ожидания, а также с некоторыми другими проблемами, такими как задержка и падение звука. Я взял USB-адаптер Bluetooth, который поддерживал еще несколько наборов функций, которые были включены в Bluetooth с момента выпуска моего ноутбука, и он работает довольно хорошо. Связь Bluetooth происходит между адаптером и динамиком, и Ubuntu видит его как USB-устройство.
