I'm using stm32f407vgt6 and trying to use USB FS mode with 

CDC library (version 1.2), what I want to know is does 

CDC library use CRC by default or not? and if yes, does that mean this connection is error free? 

Thanks in advance

Could someone help me to understand it?

What are we talking about? The CRC that the USB protocol has on its packets? This is handled by the peripheral in terms of the generation and checking of the 16-bit CRC for the packets on the wire.
