 *  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.

 *
 *  The USB stack requires the sole control over the USB controller in the microcontroller only; i.e. it does not
 *  require any additional AVR timers, etc. to operate. This ensures that the USB stack requires as few resources
 *  as possible.
 *
 *  The USB stack can be used in Device Mode for connections to USB Hosts (see \ref Group_Device), in Host mode for
 *  hosting of other USB devices (see \ref Group_Host), or as a dual role device which can either act as a USB host
 *  or device depending on what peripheral is connected (see \ref Group_OTG). Both modes also require a common set
 *  of USB management functions found \ref Group_USBManagement.

 *
 *  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.
