    Jody,

    This might be related to a too short timeout in the part of Sane's SCSI
    library for the new Linux SG driver in the 2.4 kernel.

    Please try to change the following line in sanei/sanei_scsi.c

          req->sgdata.sg3.hdr.timeout = 10000;

    (line 1892 in Sane 1.0.4) to:

          req->sgdata.sg3.hdr.timeout = 1000 * 10 * 60;
