That true that the hardware should support SAT, but even if it support 
it, linux need some patches to support SAT over USB. See 
http://thread.gmane.org/gmane.linux.scsi/43688 and the patch mentioned 
in the thread.

Unfortunately I am a bit busy to try to resubmit it. But I won't care if 
somebody improve it/resubmit it ;)

PS : there also  http://thread.gmane.org/gmane.linux.usb.general/7145
