Hi,The problem is when using USB VCP under Windows 10 on the Nucleo f746 board. The COM port is not open. When connecting to Windows 7 COM port opens.
I tried to board Nucleo l432. Works under Windows 7 and Windows 10.
Can you elaborate which example is used ? Is it the ST-link one or the F7 target mcu example : CubeMX ? Etc..
Windows 10 supports inbox VCP like a mass storage pen and there us nothing to install on pc side. It may be a usb descriptor issue - if it the example you can compare both descriptors. If it is ST-link on board you need to upgrade it.
I used the generated CUBEMX project without FREERTOS, only configured clocks and USB in VCP mode. USB for the target controller used. USB VCP from st link opens the port.CUBEMX 4.22.0.STM32F7 1.7.0.The USB port in windows 10 is fine, but my application can not open it.Creating a similar project for NUKLEO - L432 (STM32L4 1.8.1) Com port opens.
