*/

   This demo is based on the GD32F30x-EVAL board,it provides a description of 
 how to use the USBFS.

  The target of this example is to read data from and write data to USB devices using 
the CDC protocol. 
  It makes the USB device look like a serial port (NO serial cable connectors: You 
can see the data transferred to and from via USB instead of USB-to-USART bridge connection). 
  This example loops back the contents of a text file over usb port. To run the example, 
Type a message using the Pc's keyboard. Any data that shows in HyperTerminal is received 
from the device.
  This CDC_ACM Demo provides the firmware examples for the GD32F30x families.
