+ *                        USB_EVENT event, void *pdata, uint16_t size)
+ *
+ * PreCondition:    None
+ *
+ * Input:           USB_EVENT event - the type of event
+ *                  void *pdata - pointer to the event data
+ *                  uint16_t size - size of the event data
+ *
+ * Output:          None
+ *
+ * Side Effects:    None
+ *
+ * Overview:        This function is called from the USB stack to
+ *                  notify a user application that a USB event
+ *                  occured.  This callback is in interrupt context
+ *                  when the USB_INTERRUPT option is selected.
+ *
+ * Note:            None
