I noticed that many model names are a bit different in epson.desc and epkowa.desc. I don't have the detailled knowledge which model names are exactly the right ones but I assume that many of those models are on fact the same. As scanner config tools build the model lists from the *.desc files it leads to some user confusion which exact model he should select. The user may think that one model is only supported by one backend because of sightly different model names. A scanner config tool cannot find the matching backends if the model name in *.desc is sightly different than the autodetected model name and therefore the tool will not offer all backends which work in fact for the scanner to the user. Example: The labels on my scanners (i.e. what is on the hardware) are "EPSON PERFECTION 1240U" and "EPSON PERFECTION 2480 PHOTO". In epson.desc there is "Epson Perfection 1240". In snapscan.desc there is "Epson Perfection 2480". In epkowa.desk there is "EPSON Perfection 1240U" and "EPSON Perfection 2480 PHOTO". sane-find-scanner finds the "EPSON PERFECTION 1240U" as "... vendor=0x04b8 [EPSON], product=0x010b [Perfection1240] ..." and the "EPSON PERFECTION 2480 PHOTO" as "... vendor=0x04b8 [EPSON], product=0x0121 [EPSON Scanner] ..." "lsusb -v" lists the "EPSON PERFECTION 1240U" as idVendor 0x04b8 Seiko Epson Corp. idProduct 0x010b Perfection 1240 iManufacturer 1 EPSON iProduct 2 Perfection1240 and the "EPSON PERFECTION 2480 PHOTO" as idVendor 0x04b8 Seiko Epson Corp. idProduct 0x0121 iManufacturer 1 EPSON iProduct 2 EPSON Scanner Summary: Most model strings are slightly different depending where the information is stored. When case is ignored and meaningless characters (e.g. all except "abcdefghijklmnopqrstuvwxyz0123456789+") are ignored, more model strings become equivalent but trailing meaningful characters (like "U" or "PHOTO") cannot be ignored by a scanner setup tool and this leads to the above problems for the users. I would apprecialte it if at least the manufacturer and model strings in epson.desc and epkowa.desc would be the same and if possible exactly those which are autodetected. By the way: Does anybody know why model name autodetection fails for the "EPSON PERFECTION 2480 PHOTO"? Is the model name stored inside the scanner and this model reports only "EPSON Scanner" on the USB bus or has the USB system a map "model ID -> model name" where an entry for this model is missing?
