Hello All, I had some trouble to apply the new patch, but Rolf helped me to fix it.
Here comes the result with git + patch pixma_mp150.c.patch1, 3 pages in ADF. It works correct, but the timeout at the end acts weird. In the log it counts down 8 7 6...but between each line it pauses around 15-20 seconds. This scan took ages! The log comes as attachment.
