FreeRTOS - USB CDC not working with USART1

Moved from this discussion as it's linked to the embedded software USB and FreeRTOS.

My problem has always been that when USB and USART1 are working at the same time, USB as a virtual serial port is not working properly. In my code, two different threads were opened to test, one thread for usart1 and the other thread for the USB virtual serial port. Don't know what's wrong with this?
