* 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
