STM32 USB port connection problem.

Hello all,

I have problem with my USB application. I am using Atollic and CubeMx on Windows 10 system.

The USB connection gets disconnected when I enter debug mode for STM32F446RE nucleo board.

Then I tried using Nucleo H743ZI board, the board is detected but the USB is not detected. Am I missing something?

Do you speak about USB STLink?

Install the last USB/VCP driver here --> https://www.st.com/content/st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-utilities/stsw-link009.html

And be sure that your STLinkV2 firmware is up to date
