    Good news for both the SANE and the Linux1394 project:
    The EPSON scanners with Firewire (IEEE-1394) interface
    are now supported in a Linux environment using the SANE

    The IEEE-1394 interface is as easy to use as USB, but
    a lot faster (up to 400MBit/s). This makes it interesting
    for users who need a fast scan, but don't want to deal with
    all the problems associated with SCSI interfaces.

    Behind the scenes the scanner uses the SBP-2 protocol, which
    is basically just a wrapper around the SCSI commands.

    In order to get the scanner interface working, I had to modify
    the SBP-2 driver so that it would handle a non-storage device
    correctly. The EPSON scanners are therefore now the first non-
    storage devices that are supported by the SBP-2 driver.

    The instructions about how to get things working can be
    found at

    Please let me know if you run into any problems.

    Thanks to James Goodwin for his valuable tips about where to
    look for potential problems in the SBP-2 driver and to EPSON
    for providing the interface card.
