    I have a Genius ColorPage EP, which is actually a Microtek V300 parallel
    port scanner packed by Genius. I checked the FCC ID and found that it was
    made by Microtek, and the both scanners have the same specifications.

    I installed ppscsi, changed sane source code so that it would detect my
    scanner as a V300, but I still couldn't get it to work. I can insmod ppscsi,
    onscsi, and the scanner is correctly detected, but it locks when I try to
    scan anything with scanimage.

    I think maybe the problem is with the firmware, but this is wild guess. I'm
    a little clueless here: what is a firmware? :) Can I download a new version
    from somewhere and put it in my scanner? How do I do this? Or should I set
    SANE_DEBUG_MICROTEK2=30 and publish the results?

    One other question: you said you tried your scanner with a SCSI card. My
    scanner is a parallel port model, but it has a third port (one for printer,
    one for the computer, and the third) undocumented. Is is a SCSI port? Yes, I
    have never seen a SCSI port before. :)

    I would appreciate any help, it's been 2 years since I'm trying to make this
    scanner work with Linux.
