Regarding ADF support, I can tell you a difference between two situations:
ADF empty: backend hangs a while, than I can read "scanimage: sane_read:
Document feeder out of documents"
ADF with sheets loaded: operation hats instantaneously, and I can read
"scanimage: sane_read: Operation was cancelled"
I can send you some files (scanimage logs and wireshark dumps) if you want.
