+ * Compatibility HID Example:
+ * This program provides examples of the pass-through of USB-HID data and serial port
+ *  data based on compatibility HID device. And the data returned by Get_Report request is
+ *  the data sent by the last Set_Report request.Speed of UART1/2 is 115200bps.
+ *
+ * Interrupt Transfers:
+ *   UART2_RX   ---> Endpoint2
+ *   Endpoint1  ---> UART2_TX
+ *
+ *   Note that the first byte is the valid data length and the remaining bytes are
+ *   the transmission data for interrupt Transfers.
+ *
+ * Control Transfers:
+ *   Set_Report ---> UART1_TX
+ *   Get_Report <--- last Set_Report packet
