Some USB-ATA converter chips do support vendor-specific translation for special ATA commands. There was a long discussion about this in the usb-storage mailing list late last year. Read through the messages starting from here: https://lists.one-eyed-alien.net/pipermail/usb-storage/2005-November/002065.html Some significant problems remain, owing to lack of support in the SCSI stack.
