The USB-IF has historically relied on the USB 3.2 Product Matrix and USB 2.0 Product Matrix to define mandatory testing requirements for a nearly comprehensive set of USB product categories. The last category, Cables and Connectors, is not included in those documents because it is the only non-port classification. With the introduction of the USB Power Delivery Specification (PD) and USB Type-C Cable and Connector Specification (USB-C) further categorization is required to capture a clear picture of a USB-C product’s functionality and ultimately its mandatory testing requirements.
