    Hello

    I had a working HP 5P scanner on SUse 7.0 which I compiled Sane-Backend by
    hand

    I upgraded to 2.4 and SuSe 7.1 and now I get this error message with

    scanimage -d hp:/dev/sga --format tiff --mode color > /tmp/image.tif
    scanimage: sane_read: Error during device I/O

    It works with lineart or default mode - whatever that is.

    xsane says there is an i/o error

    I decided to recompile the backend and it is croaking on this line with
    this error message:

    It looks like a redefining of the scsi interfaces?

    I looked at the mailing list and saw the not to cp libs to /usr/include
    ...that seems to not to work.

    Any clues?
