- *  Functions, macros, variables, enums and types related to the management of USB communications.
+ *  Driver and framework for the USB controller hardware on the USB series of AVR microcontrollers. This module
+ *  consists of many submodules, and is designed to provide an easy way to configure and control USB host, device
+ *  or OTG mode USB applications.

+ *
+ *  Drivers for both host and device mode of the standard USB classes, for rapid application development.
+ *  Class drivers give a framework which sits on top of the low level library API, allowing for standard
+ *  USB classes to be implemented in a project with minimal user code. These drivers can be used in
+ *  conjunction with the library low level APIs to implement interfaces both via the class drivers and via
+ *  the standard library APIs.
+ *
+ *  Multiple device mode class drivers can be used within a project, including multiple instances of the
+ *  same class driver. In this way, USB Hosts and Devices can be made quickly using the internal class drivers
+ *  so that more time and effort can be put into the end application instead of the USB protocol.
+ *
+ *  The available class drivers and their modes are listed below.
