     Hello,

     could you send me a test case where 2400 dpi scan doesn't work as a 
scanimage command ? For instance something like:
export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_LOW=255
export SANE_DEBUG_GENESYS_GL124=255
scanimage -d genesys --clear-calibration --width 50.0 --height 50.0 
--resolution 2400 --mode Gray 2>scan.log >scan.pnm


changing scan parameters an color mode. Then send me the scan.log and 
scan.pnm files, and scan parameters son I can try to run the same in my 
dev environment and have a chance to reproduce it?

Regards,
     Stef
