Firstly, a developer would probably want to know if the device uses a protocol that is already supported. Otherwise, writing a new backend is not very difficult but some knowledge of the API is required. Usually, it is easier to take an existing backend and modify it to suit, at least I found it so. Out of interest, which ScanJet do you have? Cheers, Ralph
