I have Umax Astra 4400 scanner. I installed the driver from http://stef.dev.free.fr/sane/rts8891/sane-backends-rts8891.tar.gz I installed it. $sane-find-scanner -q found USB scanner (vendor=0x1606, product=0x0070, chip=rts8801/rts8891) at libusb:002:002 This is showing that scanner is detected . But
$scanimage -L No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). Please read the documentation which came with this software (README, FAQ, manpages). I tried from root user also same results I am getting. Anybody help? Thanks in advanced. -- Wishing you the very best of everything, always!!! Kousik Maiti(কৌশিক মাইতি)
