    USB CDC Receiving



      I transmit from PC to STM32F4 big packets through USB CDC FS. There aare more than 64 bytes. In this case funtion CDC_Receive_FS () is called more than one time. I want to know, can I know if the receiving frame is a single message or part of big packet, can I know the size of such big packet? (Maybe there is some flag or smth else.)
