Привет. Недавно появился у меня сканер Epson Perfection 1270. В списке поддерживаемых устройств на sane-project.org он обозначен как "good". Смотрим, что нашел scanimage: $ sudo scanimage -L device `snapscan:libusb:001:005' is a EPSON EPSON Scanner flatbed scanner Пытаемся что-то сканировать: $ sudo scanimage > image.pnm [snapscan] Scanner warming up - waiting 9 seconds. [snapscan] Scanner warming up - waiting 35 seconds. scanimage: sane_start: Error during device I/O Прогревает лампу, калибрует ее, на чем все сканирование и завершается. Включим отладку, что бы посмотреть поподробнее: $ export SANE_DEBUG_DLL=4 $ export SANE_DEBUG_SNAPSCAN=4 $ sudo scanimage -L [sanei_debug] Setting debug level of dll to 4.

В тоже время, этот сканер прекрасно работатет под 98-м мастдаем, установленным на вмварь. Посмотрел эту тему в гугле. Один человечек запостил баг на alioth.debian.org, в котором в точности описал все наблюдаемые мной симптомы: https://alioth.debian.org/tracker/index.php?func=detail&aid=301090&group_id=30186&atid=410366 В том же гугле можно видеть слова людей, которые, судя по всему смогли поставить этот сканер под sane. Что делать? Статус бага - open. Ни чего не делать, ждать, когда это зафиксят в sane-backends, если есть, что фиксить..?? Вообще, каким образом этот девайс стал называться "good" в списке поддреживаемых sane устройств? Значит, оно все-таки у кого-то работает? Но как?? -- best regards, Alexander Popov mailto:popov.ap@gmail.com
