Detailed Description

This subsystem is a framework for implementing applications where the board will act as a USB device, USB host or both.

The following diagram is a high-level overview of the USB subsystem architecture. The left side of the "USB Core" box is the USB Device framework, while the right side is the USB Host framework. An application may choose to use both or just one of the frameworks. The "OTG / transceiver" part is optional, but usually present when using a dual-role controller.
