Hi Stef, I read your post on the sane-devel mailinglist and found no reply on your request about a debug log. I also have a Canon Lide 700F scanner, which has been detected, but I am unable to scan (Ubuntu 12.04 too).
Doing a sane-find scanner works, scanning failed: sven at sven-Latitude-E5420:~$ sudo sane-find-scanner # sane-find-scanner will now attempt to detect your scanner. If the # result is different from what you expected, first make sure your # scanner is powered up and properly connected to your computer. # No SCSI scanners found. If you expected something different, make sure that # you have loaded a kernel SCSI driver for your SCSI adapter. found USB scanner (vendor=0x04a9 [Canon], product=0x1907 [CanoScan], chip=GL847) at libusb:002:006 # Your USB scanner was (probably) detected. It may or may not be supported by # SANE. Try scanimage -L and read the backend's manpage. # Not checking for parallel port scanners. # Most Scanners connected to the parallel port or other proprietary ports # can't be detected by this program. As you wrote in the mailing, I did now the following: shell and exporting the environments variables: export SANE_DEBUG_GENESYS=255 export SANE_DEBUG_GENESYS_LOW=255 export SANE_DEBUG_GENESYS_GL646=255 export SANE_DEBUG_GENESYS_GL841=255 export SANE_DEBUG_GENESYS_GL843=255 export SANE_DEBUG_GENESYS_GL847=255 export SANE_DEBUG_GENESYS_GL124=255 export SANE_DEBUG_SANEI_USB=255 xsane 2>debug.log and sent you the debug.log attached to this mail. Maybe, you can have a look at it. Thanks for your work :) Kind regards, Sven -------------- next part -------------- A non-text attachment was scrubbed...
