    That's not a big problem. I coded the ioctl_scanner() function of the
    USB stack `scanner.c' file in 2.3.x and 2.4.x linux kernels, to be used
    by the hp4200 scanner backend; and a modified version could work for
    those scanners.

    That's really a pity. I thought those 8-byte vectors could be a kind
    of a ``SCSI scanner'' like command. Anyway, rev-eng is fun (I hope).
