Hi, I am having a problem with my LiDE 50. The head in moving a bit (less thn 1 second) then stop. The following message shows up: "Failed to start scanner: Error during device I/O".
The error remains for all scanning modes: b/w, gray, color and from 75dpi to +600dpi. I use the latest back-end (1.0.18) and front-end (1.0.14) with xsane (0.991) on Fedora core 2. I send the log (SANE_DEBUG_GENESYS=255, SANE_DEBUG_GENESYS_GL841=255). Thank you for your help. Laurent __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

You can try SANE_DEBUG_SANEI_USB=255(hope this is right). That is a bit more vocal about the error(especially it tells us what errno the kernel returned. look for "sanei_usb_read_bulk: read failed:"). Do you get any suspicious kernel log entries?
