[sane-devel] State of the epjitsu backend for ScanSnap S1100/S1300i

[m. allan noah]

I have no way of knowing what the firmware does inside the scanner.
However, you could try to get a log of the S1300i in action making a
small, low resolution scan using something like Wireshark on windows.
Then we could try to compare the protocol. Unfortunately, I don't have
much time right now, but maybe it will be an easy fix.
