STM32H743I_EVAL. DP line doesn't pulled up after usb start

Hi, colleges!

I'm still working with USB. Now it is STM32H743 Eval board.

So, I tested example from Cube v1.3.0 HID-device. It didn't work. I've debuged and have seen no high signal on DP line after usb start (without V power detection). I don't now why I've no signal.

Can anybody help me? Who has experience with H743 MCU USB module?
