Is there any way to reach speed more than baud rate 115200 with virtual com port?

or any other USB communication method between STM32 and PC can speed up and ready to use for people who do not know USB at all?

you could experiment with

and test the speed.

Go to function :UART0_Config in ''Hw.config.c'' and then comment the first condition as I have done here and Now it is working with higher baudrates that are enabled in your PC.
