How to Get USBX Example to Work on STM32U575 Nucleo Board?

[khalid95]

I am working with the STM32U575 Nucleo board and trying to get the USB functionality working using one of the provided example projects "Ux_Device_CDC_ACM". I uploaded the code to the board with no problem and the USB-C is recognized by the host PC, however, I am having trouble getting it to run as expected.
Could someone guide me on:

• Any additional configurations needed in CubeMX or CubeIDE?
• Common issues to check for USB-related examples?
• How to verify if the USB peripheral is properly initialized and?

I’d appreciate any advice or resources to help troubleshoot this.
Thank you!

Hi, thanks for answering
i viewed both of them but none explain the USB_OTG in STM32U5
