  * @dev: Template descriptor for the device, including default device
  *     identifiers.
  * @strings: tables of strings, keyed by identifiers assigned during bind()
  *     and language IDs provided in control requests
+ * @needs_serial: set to 1 if the gadget needs userspace to provide
+ *     a serial number.  If one is not provided, warning will be printed.
  * @bind: (REQUIRED) Used to allocate resources that are shared across the
  *     whole device, such as string IDs, and add its configurations using
  *     @usb_add_config().  This may fail by returning a negative errno
