У меня 2 ИБП Tripplite Smart1500LCD и 2 платы Raspberry Pi 3 B+, на которых установлена Raspbian GNU/Linux 9 с ядром 4.14.79-v7+. Я испытываю ту же проблему с обоими Пис с обоими ИБП. Я использую этот учебник в качестве руководства, чтобы сделать эту работу. Сначала я заметил, что что-то не работает при вводе команды upsc :
pi@raspberrypi:~ $ upsc ups1
Error: Connection failure: Connection refused
pi@raspberrypi:~ $ sudo !!
sudo upsc ups1
Error: Connection failure: Connection refused
Мой /etc/nut/ups.conf имеет следующую запись:
[ups1]
driver = usbhid-ups -u root
port = auto
productid = 2012
desc = "Tripplite"
Я пробовал как с, так и без опции "-u root". Я даже не уверен, что это что-то делает там.
Запуск sudo upsdrvctl start дает такой результат:
Network UPS Tools - UPS driver controller 2.7.4
Network UPS Tools - Generic HID driver 0.41 (2.7.4)
USB communication driver 0.33
Using subdriver: TrippLite HID 0.82
Результат lsusb выглядит следующим образом:
Bus 001 Device 071: ID 09ae:2012 Tripp Lite
Первым делом я запустил dmesg и заметил несколько неожиданных записей. Следует отметить, что первоначально перед каждым отключением существовало сообщение MTP (IIRC):
USB is not a MTP device
поэтому я удалил mtp с помощью sudo apt-get remove --auto-remove libmtp-common
Вот вывод dmesg:

Таким образом, это воссоединение довольно часто. Я не знаю, имеет ли это какое-либо отношение к ошибке «Отказ в соединении», но это все, что я получил на данный момент. Итак, я копаю глубже.
Я вручную запускаю программу /lib/nut/usbhid-ups и получаю интересные результаты. Я удалил часть вывода для экономии места.

Я действительно не знаю все тонкости работы NUT, но мне кажется, что драйвер извлекает все соответствующие данные. Итак, вот мои вопросы:
- Почему ИБП отключаются / переподключаются?
- Это актуальная проблема?
Почему я получаю сообщение об ошибке «Отказано в соединении»?- Как мне это решить?
