+ *
+ * \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 sucessfully 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 seperate 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
+ * seperate 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_UnhandledControlRequest() 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_UnhandledControlRequest(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
