I've just installed SANE-1.0.8 under SuSE Linux 8.0 (kernel version 2.4.18). I have an Epson Perfection 1650 scanner connected via USB.
sane-find-scanner gives the following message. sane-find-scanner: found USB scanner (vendor = 0x04b8, product = 0x0110) at device /dev/usb/scanner0 sane-find-scanner: found USB scanner (vendor = 0x04b8, product = 0x0110) at device /dev/usbscanner scanimage --list-devices gives the following message. 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). The version of SANE that shipped with SuSE Linux 8.0 (1.0.7-59) is not installed: I know that that version does not support the Epson Perfection 1650 scanner; SANE-1.0.8 does. However, I have had SuSE's SANE 1.0.7-59 package previously. It did work with my Epson Perfection 1650 scanner after a fashion: the scan result was in black and white. That is the problem I'm hoping will be fixed with SANE-1.0.8.
