* Please refer to the structure #usb_device_class_config_list_struct_t.
* @param[out] handle It is out parameter, is used to return pointer of the device handle to the caller.
* The value of parameter is a pointer points the device handle, and this design is uesd to

* kinds of class handle, but there is only one device handle. So the handle points to
* a device instead of a class. And the class handle can be got from the
