Did u read the man about scanimage? http://www.sane-project.org/man/scanimage.1.html The -L or --list-devices option requests a (partial) list of devices that are available. The list is not complete since some devices may be available, but are not listed in any of the configuration files (which are typically stored in directory /etc/sane.d). This is particularly the case when accessing scanners through the network. If a device is not listed in a configuration file, the only way to access it is by its full device name. You may need to consult your system administrator to find out the names of such devices. and http://stef.dev.free.fr/sane/testing/index.html here give the debug method. export SANE_DEBUG_RTS8891=255 export SANE_DEBUG_RTS8891_LOW=255 export SANE_DEBUG_RTS88XX_LIB=255 export LD_PRELOAD=backend/.libs/libsane-rts8891.so export SANE_CONFIG_DIR=backend frontend/.libs/scanimage -d rts8891 2>rts8891-scan.log >rts8891-scan.pnm and use the method of the article to find out what is wrong with your driver. 2009/11/24 Kousik Maiti <maiti.kousik@xxxxxxxxx>: > I am Ubuntu user. > I have Umax Astra 4400 scanner.
