Good point. I have no idea, actually, it is the open function here and
I did not have this problem before. When working on the Canoscan 8800F
I often got 15 15 00 00 00 00 replies continually from the scanner
(communication failed) but this never resulted in a segfault so I
thought this cannot be a problem. But perhaps the difference in
generations between the devices is an issue. I don't know yet how to
troubleshoot this, but I will look at the pixma code and see if I can
find anything relating to generations in the endpoint handling.
