To find out if a scanner is supported and by which backend it is supported you can use the scanner search engine: http://www.sane-project.org/cgi-bin/driver.pl?manu=canon&model=LiDE30&bus=any With SANE, scanners using the same chipset are supported by the same backend. So Canon scanners may be supported by the plustek backend because they use the same hardware. E.g. Epson scanners are supported by the epson, the snapscan, the umax, and the plustek backend for the same reason. Scanner manufactureres tend to build their scanners on a few currently available chipsets. > Also when i plug this USB scanner why i got dmesg output as when i > uses xsane to scan that im age. > ppdev0: registered pardevice > ppdev0: unregistered pardevice Probably caused by a parport backend. To avoid this you can comment out everything but plustek in dll.conf (probably in /etc/sane.d). > how to find which device file this scanner is using under /dev directory? sane-find-scanner If you want to set permissions, also read README.linux: http://www.sane-project.org/README.linux Bye, Henning
