USB HS configuration does not work

On the STM32H7S3V8T6 custom board, I connected the DM and DP of HS USB to the JST connector, connected it with the Unified Daughterboard (JST TO C, https://github.com/Unified-Daughterboard/UDB-C-Legacy), and then connected it to the computer with USB A to C. However, on the computer, the device is not recognized at all. Am I wrong with the circuit configuration or the software configuration?

here's my settings

Hi @cyn7 

I'm not sure this JST connector is suitable to run at 60MHz. Maybe, USB PHY is not even clocked, or something is wrong with your hardware. Check line length matching maybe noise on VBUS, it is recommended to add a 100pF capacitor between VBUS and GND close to the Type-C connector.
