  This demo is based on the GD32450i-EVAL-V1.2 board, and it provides a description of how 
to use the USBFS/USBHS host peripheral on the GD32F4xx devices.

  Jump the JP17 to SDRAM.
  Jump the JP12/JP15 to LCD.
  The GD32F4xx devices behave as a mass storage Host that can enumerate, show content 
and write file in the attached USB flash disk. 

  If an Udisk has been attached, the user will see the information of Udisk enumeration. 
First pressing the User key will see the Udisk information, next pressing the Tamper key 
will see the root content of the Udisk, then press the Wakeup key will write file to the 
Udisk, finally the user will see the information that the MSC host demo is end.
