Hi,
the VCP driver :
https://www.st.com/en/development-tools/stsw-stm32102.html
should not be needed, as win10 + 11 have driver in system included - so maybe your enumeration going wrong...
or try thr driver - if you want.

yes, thats the website i downloaded, but STM Virtual Com port not appearing at device manager when plug usb cable into H743 Nucleo. Do you hav any idea what went wrong?

How should i know, what you doing ? (wrong or right...)
So verify you using a data cable, not a charger cable. :)
Then (which cpu ?) try a standard VCP , using HAL, just to see: it works - or not.

CDC_Transmit_FS((uint8_t *) charData, strlen(charData));

Look for CDC device example in the Cube example projects for STM32H7, adapt it for your board.

You don't need a VCP driver for late windows 8 forward. It just shows up as a COM port.
If your device isn't showing up, I'd suggest that there is something incorrect with your program running on the H7. You do have a program running on the H7, don't you? You have to provide a program that implements the device side of the VCP, it's not built into the H7.
