The Debug port facilitates OS and device driver debug. It allows the software to
communicate with an external console using a USB EHCI connection. Since the
interface to this link does not go through the normal USB EHCI stack, it allows
communication with the external console during cases where the OS is not loaded, the
USB EHCI software is broken, or where the USB EHCI software is being debugged.
Specific features of this implementation of a debug port are:
There are two operational modes for the USB debug port:
