    USB storage is real SCSI.

    ATA uses the top half of the scsi stack so ends up using the top layer
    scsi drivers. Its probably more efficient than writing new driver
    clones, especially as non disk ATA is also real SCSI (or very close).

    You can use /dev/ata if you want - its just a udev problem ;)
