Detailed Description

CDC-ACM (virtual serial) device class, app-facing API.

The class implements the CDC protocol; your app supplies callbacks for the events it cares about (port opened/closed, line coding changed, bytes received) and uses cdc_acm_send() to transmit. Built entirely on the public usbip_device.h API.

A device may carry several ports - call cdc_acm_add() once per port. Each call returns its own cdc_port, and every callback is handed the port it belongs to, so one set of callbacks can serve them all.
