  This demo is based on the GD32C113V-EVAL-V1.0 board, and it provides a description of 
how to use the USBFS host peripheral on the GD32C11x devices.

  When an USB Device is attached to the Host port, the device is enumerated and checked
whether it can support HID device, if the attached device is HID one, when the user
press the user key, the mouse or the keyboard application is launched.

  If a mouse has been attached, moving the mouse will print the position of the mouse and 
the state of button through the serial port.

  If a keyboard has been attached, pressing the keyboard will print the state of the button
through the serial port.

Note: In the USB Host HID class, two layouts are defined in the usbh_hid_keybd.h file
      and could be used (Azerty and Querty)
        //#define QWERTY_KEYBOARD
        #define AZERTY_KEYBOARD

     The User can eventually add his own layout by editing the HID_KEYBRD_Key array
     in the usbh_hid_keybd.c file.

  The demo support the functions of host suspend and wakup. The macro of USB_LOW_POWER can 
be set to 1 to test the suspend and wakeup. If you want to use the general wakeup mode, please 
press the CET key. If you want to use the remote wakeup mode, please operating device, such as 
move the mouse or press the keyboard. If you want the program to continue running, please press 
the CET key.
