STM32F429 - Discovery card Micro Usb COM port not showing in Windows 10!

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.

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.

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