I assumed that you're using bash or similar shell. $ export SANE_DEBUG_DLL=3 $ scanimage -L The debug messages will tell you whether your backend was loaded by the libsane-dll.so. Possibly that you didn't export the API functions as sane_khf_init, sane_khf_exit etc. Regards -- Wittawat Yamwong Hannover, Germany
