     when scanning at these resolution, the motor is slow and very 
silent. So it takes time to scan. In odrer to speed scan, use geometry 
parameters to reduce the amount of data (a full 2400 dpi scan is about 
1,7 Gb) and let the scanner time to complete.
     If after a few minutes, nothing is moving, run scanimage with debug 
traces enabled, so we can try to understand what may happening:

scanimage -d genesys --clear-calibration --resolution 2400 --mode Color 
-l 20 --height 10 --width 180 2>rl.log >rl.pnm

then send the rl.log debug file.
