I'm not aware of any USB-Bridge supporting this standard. For the Cypress chipset, "-d usbcypress" is required. But (AFAIK) Cypress does only provide USB->PATA bridges. So if the Maxtor OneTouch is USB->SATA, it likely contains another chipset which is not compatible with Cypress. Cheers, Christian |
