  // You should declare your own @USBD_DescriptorsTypeDef variable, and
  // the initialize the contents with your functions by filed names, but
  // insert this marco in the top:
  //   const USBD_DescriptorsTypeDef CustomDescriptorHandlers = {

  //  In the example above only @GetDeviceDescriptor and @GetInterfaceStrDescriptor
  //  are implemeted in the class and overrided in the structure, all others 
  // handlers are initialized by the default handler-functions.
