     Hello,

     it is a matter of minutes not hours. Something isn't going right. 
Could you send the debug log a small gray scan with the following commands:
export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_LOW=255
export SANE_DEBUG_GENESYS_GL847=255
export SANE_DEBUG_GENESYS_GL124=255
scanimage -d genesys --clear-calibration --width 50.0 --height 50.0 
--mode Gray --resolution 2400  2>scan.log >scan.pnm

Regards,
     Stef
