  This demo is based on the GD32VF103R-START-V1.0 board, and it provides a description of how
to use the USBFS host peripheral on the GD32VF103V devices.

  Insert the OTG cable to the USB_FS port. Then download it to the start board and run.

  If an Udisk has been attached, the LED4 will be light on, indicating that the U disk is
successfully connected. And the LED 2 flickers slowly, indicating that the U disk has been
successfully enumerated.

  First pressing the User key, LED2 will flickers quickly, indicating that the host has
identified the U disk.

  Then pressing the User key again, LED2 will flickers slowly, indicating that the contents
of the U disk have been read correctly.

  The third press of the User button will write files to the U disk and the user will see
both the LED 1 and the LED 2 light up, indicating the end of the MSC host example.

 Finally, pull out the U disk and you can see that the LED 4 is on.
