+ * - LUFA/Drivers/USB/Class/Device/CDC.c <i>(Makefile source module name: LUFA_SRC_USBCLASS)</i>
+ *
+ * \section Module Description
+ * Device Mode USB Class driver framework interface, for the CDC USB Class driver.
+ *
+ * \note There are several major drawbacks to the CDC-ACM standard USB class, however
+ * it is very standardized and thus usually available as a built-in driver on
+ * most platforms, and so is a better choice than a proprietary serial class.
+ *
+ * One major issue with CDC-ACM is that it requires two Interface descriptors,
+ * which will upset most hosts when part of a multi-function "Composite" USB
+ * device, as each interface will be loaded into a separate driver instance. To
+ * combat this, you should use the "Interface Association Descriptor" addendum to
+ * the USB standard which is available on most OSes when creating Composite devices.
+ *
+ * Another major oversight is that there is no mechanism for the host to notify the
+ * device that there is a data sink on the host side ready to accept data. This
+ * means that the device may try to send data while the host isn't listening, causing
+ * lengthy blocking timeouts in the transmission routines. To combat this, it is
+ * recommended that the virtual serial line DTR (Data Terminal Ready) be used where
+ * possible to determine if a host application is ready for data.

+ * 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.
+ */
+
+/** @defgroup Group_USBClassDrivers USB Class Drivers
+ *
+ * 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.

+ * \section Sec_UsingClassDrivers Using the Class Drivers
+ * To make the Class drivers easy to integrate into a user application, they all implement a standardized
+ * design with similarly named/used function, enums, defines and types. The two different modes are implemented
+ * slightly differently, and thus will be explained separately. For information on a specific class driver, read
+ * the class driver's module documentation.
+ *
+ * \subsection SSec_ClassDriverDevice Device Mode Class Drivers
+ * Implementing a Device Mode Class Driver in a user application requires a number of steps to be followed. Firstly,
+ * the module configuration and state structure must be added to the project source. These structures are named in a
+ * similar manner between classes, that of <i>USB_ClassInfo_<b>{Class Name}</b>_Device_t</i>, and are used to hold the
+ * complete state and configuration for each class instance. Multiple class instances is where the power of the class
+ * drivers lie; multiple interfaces of the same class simply require more instances of the Class Driver's ClassInfo
+ * structure.
+ *
+ * Inside the ClassInfo structure lies two sections, a <i>Config</i> section, and a <i>State</i> section. The Config
+ * section contains the instance's configuration parameters, and <b>must have all fields set by the user application</b>
+ * before the class driver is used. Each Device mode Class driver typically contains a set of configuration parameters
+ * for the endpoint size/number of the associated logical USB interface, plus any class-specific configuration parameters.
+ *
+ * The <i>State</i> section of the ClassInfo structures are designed to be controlled by the Class Drivers only for
+ * maintaining the Class Driver instance's state, and should not normally be set by the user application.
+ *
+ * The following is an example of a properly initialized instance of the Audio Class Driver structure:
+ *
+ * \code
+ * USB_ClassInfo_Audio_Device_t My_Audio_Interface =
+ * {
+ * .Config =
+ * {
+ * .StreamingInterfaceNumber = 1,
+ *
+ * .DataINEndpointNumber = 1,
+ * .DataINEndpointSize = 256,
+ * },
+ * };
+ * \endcode
+ *
+ * \note The class driver's configuration parameters should match those used in the device's descriptors that are
+ * sent to the host.
+ *
+ * To initialize the Class driver instance, the driver's <i><b>{Class Name}</b>_Device_ConfigureEndpoints()</i> function
+ * should be called in response to the \ref EVENT_USB_Device_ConfigurationChanged() event. This function will return a
+ * boolean value if the driver successfully initialized the instance. Like all the class driver functions, this function
+ * takes in the address of the specific instance you wish to initialize - in this manner, multiple separate instances of
+ * the same class type can be initialized like thus:
+ *
+ * \code
+ * void EVENT_USB_Device_ConfigurationChanged(void)
+ * {
+ * LEDs_SetAllLEDs(LEDMASK_USB_READY);
+ *
+ * if (!(Audio_Device_ConfigureEndpoints(&My_Audio_Interface)))
+ * LEDs_SetAllLEDs(LEDMASK_USB_ERROR);
+ * }
+ * \endcode
+ *
+ * Once initialized, it is important to maintain the class driver's state by repeatedly calling the Class Driver's
+ * <i><b>{Class Name}</b>_Device_USBTask()</i> function in the main program loop. The exact implementation of this
+ * function varies between class drivers, and can be used for any internal class driver purpose to maintain each
+ * instance. Again, this function uses the address of the instance to operate on, and thus needs to be called for each
+ * separate instance, just like the main USB maintenance routine \ref USB_USBTask():
+ *
+ * \code
+ * int main(void)
+ * {
+ * SetupHardware();
+ *
+ * LEDs_SetAllLEDs(LEDMASK_USB_NOTREADY);
+ *
+ * for (;;)
+ * {
+ * Create_And_Process_Samples();
+ *
+ * Audio_Device_USBTask(&My_Audio_Interface);
+ * USB_USBTask();
+ * }
+ * }
+ * \endcode
+ *
+ * The final standardized Device Class Driver function is the Control Request handler function
+ * <i><b>{Class Name}</b>_Device_ProcessControlRequest()</i>, which should be called when the
+ * \ref EVENT_USB_Device_ControlRequest() event fires. This function should also be called for
+ * each class driver instance, using the address of the instance to operate on as the function's
+ * parameter. The request handler will abort if it is determined that the current request is not
+ * targeted at the given class driver instance, thus these methods can safely be called
+ * one-after-another in the event handler with no form of error checking:
+ *
+ * \code
+ * void EVENT_USB_Device_ControlRequest(void)
+ * {
+ * Audio_Device_ProcessControlRequest(&My_Audio_Interface);
+ * }
+ * \endcode
+ *
+ * Each class driver may also define a set of callback functions (which are prefixed by "CALLBACK_"
+ * in the function's name) which <b>must</b> also be added to the user application - refer to each
+ * individual class driver's documentation for mandatory callbacks. In addition, each class driver may
+ * also define a set of events (identifiable by their prefix of "EVENT_" in the function's name), which
+ * the user application <b>may</b> choose to implement, or ignore if not needed.
+ *
+ * The individual Device Mode Class Driver documentation contains more information on the non-standardized,
+ * class-specific functions which the user application can then use on the driver instances, such as data
+ * read and write routines. See each driver's individual documentation for more information on the
+ * class-specific functions.
+ *
+ * \subsection SSec_ClassDriverHost Host Mode Class Drivers
+ * Implementing a Host Mode Class Driver in a user application requires a number of steps to be followed. Firstly,
+ * the module configuration and state structure must be added to the project source. These structures are named in a
+ * similar manner between classes, that of <i>USB_ClassInfo_<b>{Class Name}</b>_Host_t</i>, and are used to hold the
+ * complete state and configuration for each class instance. Multiple class instances is where the power of the class
+ * drivers lie; multiple interfaces of the same class simply require more instances of the Class Driver's ClassInfo
+ * structure.
+ *
+ * Inside the ClassInfo structure lies two sections, a <i>Config</i> section, and a <i>State</i> section. The Config
+ * section contains the instance's configuration parameters, and <b>must have all fields set by the user application</b>
+ * before the class driver is used. Each Device mode Class driver typically contains a set of configuration parameters
+ * for the endpoint size/number of the associated logical USB interface, plus any class-specific configuration parameters.
+ *
+ * The <i>State</i> section of the ClassInfo structures are designed to be controlled by the Class Drivers only for
+ * maintaining the Class Driver instance's state, and should not normally be set by the user application.
+ *
+ * The following is an example of a properly initialized instance of the MIDI Class Driver structure:
+ *
+ * \code
+ * USB_ClassInfo_MIDI_Host_t My_MIDI_Interface =
+ * {
+ * .Config =
+ * {
+ * .DataINPipeNumber = 1,
+ * .DataINPipeDoubleBank = false,
+ *
+ * .DataOUTPipeNumber = 2,
+ * .DataOUTPipeDoubleBank = false,
+ * },
+ * };
+ * \endcode
+ *
+ * To initialize the Class driver instance, the driver's <i><b>{Class Name}</b>_Host_ConfigurePipes()</i> function
+ * should be called in response to the host state machine entering the \ref HOST_STATE_Addressed state. This function
+ * will return an error code from the class driver's <i><b>{Class Name}</b>_EnumerationFailure_ErrorCodes_t</i> enum
+ * to indicate if the driver successfully initialized the instance and bound it to an interface in the attached device.
+ * Like all the class driver functions, this function takes in the address of the specific instance you wish to initialize -
+ * in this manner, multiple separate instances of the same class type can be initialized. A fragment of a Class Driver
+ * based Host mode application may look like the following:
+ *
+ * \code
+ * switch (USB_HostState)
+ * {
+ * case HOST_STATE_Addressed:
+ * LEDs_SetAllLEDs(LEDMASK_USB_ENUMERATING);
+ *
+ * uint16_t ConfigDescriptorSize;
+ * uint8_t ConfigDescriptorData[512];
+ *
+ * if (USB_Host_GetDeviceConfigDescriptor(1, &ConfigDescriptorSize, ConfigDescriptorData,
+ * sizeof(ConfigDescriptorData)) != HOST_GETCONFIG_Successful)
+ * {
+ * LEDs_SetAllLEDs(LEDMASK_USB_ERROR);
+ * USB_HostState = HOST_STATE_WaitForDeviceRemoval;
+ * break;
+ * }
+ *
+ * if (MIDI_Host_ConfigurePipes(&My_MIDI_Interface,
+ * ConfigDescriptorSize, ConfigDescriptorData) != MIDI_ENUMERROR_NoError)
+ * {
+ * LEDs_SetAllLEDs(LEDMASK_USB_ERROR);
+ * USB_HostState = HOST_STATE_WaitForDeviceRemoval;
+ * break;
+ * }
+ *
+ * // Other state handler code here
+ * \endcode
+ *
+ * Note that the function also required the device's configuration descriptor so that it can determine which interface
+ * in the device to bind to - this can be retrieved as shown in the above fragment using the
+ * \ref USB_Host_GetDeviceConfigDescriptor() function. If the device does not implement the interface the class driver
+ * is looking for, if all the matching interfaces are already bound to class driver instances or if an error occurs while
+ * binding to a device interface (for example, a device endpoint bank larger that the maximum supported bank size is used)
+ * the configuration will fail.
+ *
+ * Once initialized, it is important to maintain the class driver's state by repeatedly calling the Class Driver's
+ * <i><b>{Class Name}</b>_Host_USBTask()</i> function in the main program loop. The exact implementation of this
+ * function varies between class drivers, and can be used for any internal class driver purpose to maintain each
+ * instance. Again, this function uses the address of the instance to operate on, and thus needs to be called for each
+ * separate instance, just like the main USB maintenance routine \ref USB_USBTask():
+ *
+ * \code
+ * int main(void)
+ * {
+ * SetupHardware();
+ *
+ * LEDs_SetAllLEDs(LEDMASK_USB_NOTREADY);
+ *
+ * for (;;)
+ * {
+ * switch (USB_HostState)
+ * {
+ * // Host state machine handling here
+ * }
+ *
+ * MIDI_Host_USBTask(&My_Audio_Interface);
+ * USB_USBTask();
+ * }
+ * }
+ * \endcode
+ *
+ * Each class driver may also define a set of callback functions (which are prefixed by "CALLBACK_"
+ * in the function's name) which <b>must</b> also be added to the user application - refer to each
+ * individual class driver's documentation for mandatory callbacks. In addition, each class driver may
+ * also define a set of events (identifiable by their prefix of "EVENT_" in the function's name), which
+ * the user application <b>may</b> choose to implement, or ignore if not needed.
+ *
+ * The individual Host Mode Class Driver documentation contains more information on the non-standardized,
+ * class-specific functions which the user application can then use on the driver instances, such as data
+ * read and write routines. See each driver's individual documentation for more information on the
+ * class-specific functions.
