  53  *  \section Module Description
  54  *  Driver and framework for the USB controller hardware on the USB series of AVR microcontrollers. This module
  55  *  consists of many submodules, and is designed to provide an easy way to configure and control USB host, device
  56  *  or OTG mode USB applications.
  57  *
  58  *  The USB stack requires the sole control over the USB controller in the microcontroller only; i.e. it does not
  59  *  require any additional AVR timers, etc. to operate. This ensures that the USB stack requires as few resources
  60  *  as possible.
  61  *
  62  *  The USB stack can be used in Device Mode for connections to USB Hosts (see \ref Group_Device), in Host mode for
  63  *  hosting of other USB devices (see \ref Group_Host), or as a dual role device which can either act as a USB host
  64  *  or device depending on what peripheral is connected (see \ref Group_OTG). Both modes also require a common set
  65  *  of USB management functions found \ref Group_USBManagement.

  69  *  @defgroup Group_USBClassDrivers USB Class Drivers
  70  *
  71  *  Drivers for both host and device mode of the standard USB classes, for rapid application development.
  72  *  Class drivers give a framework which sits on top of the low level library API, allowing for standard
  73  *  USB classes to be implemented in a project with minimal user code. These drivers can be used in
  74  *  conjunction with the library low level APIs to implement interfaces both via the class drivers and via
  75  *  the standard library APIs.
  76  *
  77  *  Multiple device mode class drivers can be used within a project, including multiple instances of the
  78  *  same class driver. In this way, USB Hosts and Devices can be made quickly using the internal class drivers
  79  *  so that more time and effort can be put into the end application instead of the USB protocol.
  80  *
  81  *  The available class drivers and their modes are listed below.
