Hello Rolf, I'm sorrry, that this took so long time, but I replaced my pc and restarted from zero. That's why I used the wrong library version last time.
But I think there are still issues. I scanned 3 pages. And if I cause a paper input error for example by holding it back with my hand, I can press cancel and OK on the scanner, restart scanimage and it will work. This seems to be fixed now. But: The pages have the wrong aspect ratio, they are far too long. And the "resolution"-parameter is ignored. I scanned with 300dpi and the images have just around 2MB and are of low quality. I don't know why, but with patch1-5 it worked better. Did you change something or did you just sum up the patches? I'm still unsure, if it's a problem with my setup...
