замена 42.1 на leap 15.0. Проблема при подключении сканера МФУ Brother DCP-7070DWR.
Сканер МФУ не подключается через YaST (сканеры не распознаны). Т.е. в системе (через xscan) сканирование невозможно. Принтер МФУ работает нормально.
sane, sane-backends, sane-backends-autoconfig установлены

при запуске в YaST вкладки "сканер" получаем в логе:

не помогли: замена драйверов (сейчас стоят 4-е), переустановка, проверка доступа.

программа VueScan соединяется со сканером без проблем.
