Well, thank you anyway. The hint is valid, of 
course. Somehow something isn't working as 
expected on my system. Might be interesting to 
track down, which, of course, isn't doing any 
scanning for me. :)

To keep the communication more useful, 
topic-wise: is plustek backend (20150807) really 
supposed to scan full A4 in B/W 600 dpi on Canon 
LIDE 25 for like one minute or more? Scanning in 
600 dpi B/W used to go much faster, as far as I 
can recall, not on this hardware, though.
