/* @Note
* 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
