The main reason this exists is that I need access to USB flash memory on small embedded systems where I cannot afford to have CAM+SCSI layers in the kernel due to strick size limitations. A nice side effect is that I now also can use external USB disks and CDROM/DVD drives with the same benefits. I could also much easier support those USB storage devices that just present the ATA register file as is, but so far I havn't been able to locate any of those. Drawbacks is that it has not been around for so long so bugs etc might lurck in there as usual... -Søren
