Hi everyone, 
 I am a newbie with the KIT STM32F4 Discovery. So, now I want to use USART to send and receive data through Virtual Com Port (using Micro USB) but I have some problems with this. I can't find any COM in Device Manager in the PC. I 've read many threads about this problem but now, It's only a mess in my mind. So, someone please tells me Steps to run the USART project. one more question,  are there any libraries for this ? My English is bad , so please forgive me if I say anything wrong. Thank you very much. 2.PNG1.PNG
