&par Example Description

This example describes how to use USBD to simulate a WINUSB device.
Program will send hello + num string to USB host. And when WINUSB 
device receive data will send back the same data to USB host.

&par Hardware Description

The USART1 is configured as follows:
    - TX:PA9, RX:PA10
    - BaudRate = 115200 baud
    - Word Length = 8 Bits
    - One Stop Bit
    - No parity
    - Hardware flow control disabled (RTS and CTS signals)
    - Receive and transmit enabled

    - VCC5V         ----------> VBUS
    - USBD_DM(PA11) ----------> USB_DN
    - USBD_DP(PA12) ----------> USB_DP
    - GND           ----------> GND
