    I have an HP ScanJet 3300 which I would like to get working with SANE. I
    am willing (though very time-constrained) to write a backend for it, but I
    am still in the collecting information phase. Here is what I have found
    out so far...

    1) HP has not been forthcoming with the technical documents, so it looks
    like a reverse-engineering job.

    2) The scanner has 4 main chips on it.
       a) is 256k buffer.
       b) appears to be the main scanner control chip.
       c) is an 8bit A/D.
       d) appears to be the USB interface controller.
            a) EliteMT -25j
               9912s
               M11B416256A
            b) NIASH00014
               F7UJ0-000
               9939
            c) NIPEDC0804
            d) ESIC
               ES8100QA
               F3A329935

    3) I have run USBsniff on the scanner under windows, but I don't know
    enough about the output to do much diagnosis on it yet. I'll look at it
    more later.

    If anyone has some more information for me I would appreciate it. Thanks.
