I tried with different dpi resolutions. Most of the time  it starts with 
the horrible noise but sometimes it works. I'd say every 5th try works.
Even calibrating under XSane results in that noise...

I searched for a plustek config file but could not find it.

By the way, there is a hint about "awfull noise" in the FAQ.gz at
