I began hacking a uata (USB->ATA) bridge driver with sos's help today.

It might help you. Some of the cheaper enclosures use USB->ATA bridge
chips which aren't handled by the standard umass driver.

Before anyone asks, these are evil, and don't talk SCSI/UFI/etc, they
talk ATA task file register over USB, so branching off ata is more
appropriate; I should be able to leverage most of the existing ATAng
code base for this.
