    I've had exactly the same problem trying to get the XPA on the
    6350C working with VueScan.

    It appears that the root of the problem is that it's a 5 x 5 inch
    scan area instead of the whole flatbed. It isn't clear if the coordinates
    of the scan area are adjusted to be 5 x 5 inches or if the coordinates
    have to be offset to the calibration area and the 5x5 inch area.

    Unfortunately, I don't have one of these myself, but have only gotten
    log files from people who own them. It would be useful if someone
    could get a log of the USB commands that the HP software uses
    to talk to the transparency adapter. The tool that's been useful
    for me in the past is at:

    If someone wants to get scsi traces from this scanner, they can
    use my scsi tracing tool that intercepts and logs ASPI commands.
    It can be downloaded from:
