I'm using STM32F407 Discovery-1, I use USB CDC to send and receive data from terminal. Everything ok but issue that I need re-connect port to transmit and receive data, but i remember that when i used STM32F407 Discovery , every when i upload new code, i don't need to re-connect port. I use CubeMx 4.14 for both STM32F407 Discovery versions. Please help me to resolve this problem. Sorry for bad my english.
