    Hi Chris

    A few experiments:

    1) Still using the original snapscan driver of 1.0.3, but patched:
      The 1212U_2 (mine) does the following:
       - as 1236S: only B/W and Line Art
       - as Acer 620: Color, but vertically stretched (about 3 times)
       - as Snapscan 310/300: Size seems to be correct, but colors
         are separated (RGB) and image is is cut into stripes (displaced)

    2) Using the sourceforge driver, which had 1212U in the .h file:
      I Had to add 1212U_2 there, else it didn't recognize it.
      Then, the same problem as 310/300 above.

    This should be some (simple?) juggling with sizes. Probably due to
    different organizing of the data coming from the scanner. Maybe due
    to the 36 bit scheme? I'll try and find where this is done, though I'd
    appreciate any hint as to where to look.

    Maybe I could send you a small image - this could indicate where
    the problem is.

    Thanks for all the help!
