Thank you, I will look into it.
But now I found the cause of my problem: there is a conflict between USB and USART3. In my specific case, I intend to use USART3 as RS-485. When I enable USART3, USB stops. I checked the pins and everything is fine. In addition, some leds (which I have set but not tested yet) turn on and blink. I have no idea about what it could be. Could you give me some insight about this usb-uart3 issue?
