ALT Linux Bugzilla – #39755

Надеюсь не идёт речь о проприетарном драйвере ?

Если несложно, хотя бы пару-тройку бэкендов приведите, чтобы было с чего начать.

В приведенном примере драйвер сканирования от производителя.

Но суть проблемы в том, что при прочих равных условиях на 8 платформе xsane работает, а на 9 не работает.

Регрессию можно увидеть например на офисном МФУ HP M426fdn

При подключении Ноутбука с Альт 8 СП (по USB) xsane работает.
При подключении Альт рабочая станция 9 не работает.
Альт 8 СП (9 платформа) не работает.

Покажите вывод 
sane-find-scanner
и
scanimage -L

лучше, если с обеих платформ.

Все работает. В следующем сообщении приведу вывод с Альт рабочая станция 9.

С офисным МФУ HP M426fdn проблему решили. Спасибо Андрею Черепанову.
Помогло обновление hp-lib.

Но хочу обратить внимание, что на Альт 8СП это не требовалось. Все работало "из коробки".
(пользователя необходимо было добавить в группу lp)

Результат проверки актуальности

Состояние:
Случай HP исправлен обновлением HPLIP, но исходный Epson M3170 не перепроверялся.

Рекомендация:
провести ручной ретест с текущим xsane
