I have the STM32F429 Discovery development board. I want to send and receive data from the USB port. I will use Virtual Com Port for this. When I connect the Micro USB port on the card to the computer, it does not appear as a device. I use Keil as the compiler. My operating system is Windows 10.
Solved! Go to Solution.

You have installed a driver on your PC, but apparently there is no driver on the STM32F429.
Try compiling and installing an USB example from STM32CubeF4.

"data cable is not visible" ? You can't see the cable plugged into the board? I don't know how to parse this, seems like all is working correctly to me.

I installed the drivers that STM gave but it doesn't see micro usb connection in any way.

And what is that virtual COM Port thing in the device manager?

My problem is that it does not appear as a device when I connect micro usb. The programming cable of the com5 card shown in the picture, mini-b.

You need some software on the STM32F429 to configure the USB port as a serial communication device, and handle requests from the PC.
If there is no software to do that, the USB cable is just a piece of dangling wire as far as the PC can tell.

I installed the driver I mentioned above for this. But the computer does not see the card still connected. What should i do for the computer to see the micro usb connection ?? Is there anyone who can help ?

Before seeing your suggestion, I solved my problem by using the example below. Thank you to Mr. Majerle and you.
