If you don't specify the scanner to scanimage with the -d option, then 
it will poll around all the backends to obtain a list of the available 
scanners first. This typically can take quite a good few seconds.

Run scanimage -L to get a list of device names, then add that device 
name with the -d option to your scan line. I believe this will solve 
your problem.
