Я управляю ореховый сервер подключен к Tripp Lite SMART1500LCD через USB. Устройство ведет себя неожиданно, и я вижу следующие сообщения ядра:

Вы можете видеть, как увеличивается номер устройства каждый раз при повторном подключении ИБП.
Я заменил USB-кабель и попробовал разные USB-порты, но это ни на что не повлияло.
Кроме того, я вижу эту ошибку каждые 22 секунды.

Если я вручную запустил драйвер, это будет выход с удаленной сводкой мощности ИБП:

Что вызывает отключение ИБП?
Вдохновленный эта почта, решение для меня до сих пор заключалось в создании нового правила udev:
# /etc/udev/rules.d/62-nut-usbups.rules
SUBSYSTEM!="usb", GOTO="nut-usbups_rules_end"
# TrippLite
# e.g. TrippLite SMART1500LCD - usbhid-ups
ACTION=="add|change", SUBSYSTEM=="usb|usb_device", SUBSYSTEMS=="usb|usb_device", ATTR{idVendor}=="09ae", ATTR{idProduct}=="2012", MODE="664", GROUP="nut", RUN+="/sbin/upsdrvctl stop; /sbin/upsdrvctl start"
LABEL="nut-usbups_rules_end"
И измените pollinterval в моем ups.conf:
# /etc/nut/ups.conf
pollinterval = 1
[ups]
driver = usbhid-ups
port = auto
desc = "Tripp Lite SMART1500LCD"
vendorid = 09ae
productid = 2012
Пока что за 24 часа не было ни отключений USB, ни предупреждений об устаревших данных ИБП.
Могут быть более изящные решения, но пока это работает.
