H753ZI - UsbX Device not recognized error

Hi,

I'm having an issue implementing USB device composite functionality on my Nucleo-H753ZI board. I've been following the tutorial series at https://community.st.com/t5/stm32-mcus/how-to-implement-the-usb-device-composite-class-in-stm32-using/ta-p/645017 to set up a composite device using USB_OTG_FS in device-only mode.

I've also examined and tried implementing the example code from the official ST repository at https://github.com/STMicroelectronics/x-cube-azrtos-h7/ but I still couldn't solve the issue. 

USB_OTG_FS:

Thank you for your valuable response. I fixed the problem. Even though the clock settings were properly configured for USB at 48 MHz in both cases, I believe I was experiencing issues due to my HSE frequency configuration.

I'm sharing both the problematic and working .ioc files for clock configurations.
