/* @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
