Custom USB Class troubles

Georg D

After connecting custom USB device, device appears on Windows Device Manager, during
tracing these functions are called:

 usbd_cls_init
 usbd_cls_sof

But the following functions are never called:

 usbd_cls_dev_req
 usbd_cls_ep_req
 usbd_cls_if_req

Main function is consist only from empty loop:

while(1)
   ;


Do I need to pool some USB driver function in main?
