Call USBD_HID_CfgAdd()
Finally, once the HID class instance has been created, you must add it to a specific
configuration.
Listing 9-1 illustrates the use of the previous functions for initializing the HID class.
static USBD_HID_CALLBACK App_USBD_HID_Callback = {
App_USBD_HID_GetFeatureReport,
App_USBD_HID_SetFeatureReport,
App_USBD_HID_GetProtocol,
App_USBD_HID_SetProtocol,
};

CPU_BOOLEAN
{
App_USBD_HID_Init (CPU_INT08U
