I'm having trouble getting scanning working with my Epson CX7800. I'm running Debian linux with kernel 2.6.12.2.
First tried with the epson backend. Added usb 0x4b8 0x081f epson.conf. Then # sane-find-scanner found USB scanner (vendor=0x04b8 [EPSON], product=0x081f [USB2.0 MFP(Hi-Speed)]) at libusb:003:006 # scanimage -L device `v4l:/dev/video0' is a Noname WinTV PVR 350 virtual device device `epson:libusb:003:006' is a Epson Unknown model flatbed scanner But # scanimage -d epson:libusb:003:006 scanimage: sane_start: Operation not supported (Debug output at http://jdc.math.uwo.ca/tmp/epson.debug ) I also tried the epkowa backend, installed using the rpm iscan-1.17.0-1.c2.i386.rpm at http://www.avasys.jp/english/linux_e/dl_spc.html: # scanimage -d epkowa:libusb:003:006 > /tmp/scan This has worked about 3 out of the 10 or 12 times I've tried it; most of the time it gives: # scanimage -d epkowa:libusb:003:006 > /tmp/scan scanimage: sane_start: Error during device I/O (Debug output at http://jdc.math.uwo.ca/tmp/epkowa.debug ) Let me know if there's any other information that would help debug either of these issues. Thanks, Dan
