в здравом уме не находит HP Scanjet G3110

Я пытаюсь установить HP Scanjet G3110, который мне дали, на мой сервер печати, на котором работает Ubuntu 14.04.3. Я установил sane и серверную часть hp3900, которая указана здесь как базовая поддержка для этой модели здесь , но я не могу найти нормального, чтобы найти сканер. Я проверил, что etc / sane.d / dll.conf содержит ссылку на hp3900 и что hp3900.conf имеет

# HP Scanjet G3110
usb 0x03f0 0x4305

и что никакие другие строки не имеют такой же usb 0x03f0 0x4305. Результаты нескольких соответствующих команд следуют. Что еще мне следует попробовать, или у кого-то есть еще одно преимущество, которое я могу отследить?

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
