The USB Host Port controller is fully compliant with the Open HCI specification. The USB Host Port User Interface
(registers description) can be found in the Open HCI Rev 1.0 Specification available on
http://h18000.www1.hp.com/productinfo/development/openhci.html. The standard OHCI USB stack driver can be
easily ported to Atmel’s architecture, in the same way all existing class drivers run without hardware specialization.
This means that all standard class devices are automatically detected and available to the user’s application. As an
example, integrating an HID (Human Interface Device) class driver provides a plug & play feature for all USB key-
boards and mouses.
