Detailed Description

USB Communications Device Class (CDC) public header.

Header follows the Class Definitions for Communications Devices Specification (CDC120-20101103-track.pdf), PSTN Devices Specification (PSTN120.pdf) and Ethernet Control Model Devices Specification (ECM120.pdf). Header is limited to ACM and ECM Subclasses.
