Advanced Configuration and Power Interface Specification

Advanced Configuration and Power Interface Specification
Type C connector - USB2 and SS without Switch receptacles
These implement the USB2 signal pair and a Functional Switch by connecting each
receptacle SuperSpeed signal pair to a separate USB Host Controller port.
Note: Refer to section 4.5.1.1 in the USB Type-C Specification for more information.
Example
The following is an example of a port characteristics object implemented for a USB host controller’s
root hub where:
• Three Ports are implemented; Port 1 is not user visible/not connectable and Ports 2 and 3 are
user visible and connectable.
• Port 2 is located on the back panel
• Port 3 has an integrated 2 port hub. Note that because this port hosts an integrated hub, it is
therefore not sharable with another host controller (e.g. If the integrated hub is a USB2.0 hub,
the port can never be shared with a USB1.1 companion controller).
• The ports available through the embedded hub are located on the front panel and are adjacent to
one another.
