Thanks for pointing out that bug report.
I think that my issue might be different. I forgot to mention, but starting a new scan (second scanimage command) yields the same results, i.e. first 2 pages are fine.
I managed to get the git build to run locally, and I'm testing it, so my initial question is answered.
I suspect my hardware is shot and needs extra resets. Is there any other user of UT16 that can confirm?
