* 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

* To initialize the Class driver instance, the driver's <tt><b>{Class Name}</b>_Host_ConfigurePipes()</tt> function
- * should be called in response to the host state machine entering the \ref HOST_STATE_Addressed state. This function
+ * should be called in response to the \c EVENT_USB_Host_DeviceEnumerationComplete() event firing. This function will
* will return an error code from the class driver's <tt><b>{Class Name}</b>_EnumerationFailure_ErrorCodes_t</tt> 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 -
* based Host mode application may look like the following:
*

+ * Note that the function also requires 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.
*
+ * To complete the device enumeration after binding the host mode Class Drivers to the attached device, a call to
+ * \c USB_Host_SetDeviceConfiguration() must be made. If the device configuration is not set within the
+ * \c EVENT_USB_Host_DeviceEnumerationComplete() event, the host still will assume the device enumeration has failed.

* Once initialized, it is important to maintain the class driver's state by repeatedly calling the Class Driver's
