* 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.

+ * 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

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