USB VCP with STM32H7 does not work correctly

[NTaha.1]

Hello everyone,

I have a Project with STM32H745(Nucleo-H745ZI-Q). in this project I need to send data periodically to PC over VCP. I have configured everything and it works fine. But when I connect the device to the USB on the front side of my PC, the PC receives a small amount of data, and Dann stop( the MCU still sends data, USB on the back side works properly). As serial terminal, I tried Hterm and Hercules. With both, I had the same problem. VCP-driver i have "en.stsw-stm32102_v1.5.0".

Did anyone face such a Problem?

When establishing the communication with the VCP, the PC sends a small amount of setup data to the device, and it responds accordingly. This is normal
