No CDC ACM/COM port is being formed for USB Device code for STM32U5G-DK1

[Sudarshan]

Hello,

I am making a new project by importing the .ioc file of example code "Ux_Device_CDC_ACM" of STM32U5G-DK2. All the .c files of USB_stack and Azure_RTOS are also copied from the example project. Both, example project and My project, look same. My project builds also successfully. But no COM/ACM port is being formed after loading the project to STM32U5G-DK1 whereas, COMM port is being formed with Example project. 

What can be the reason ? Please help.

NOTE: USB Device mode Example project in repository is provided for STM32U5G-DK2 and not for DK1. So. we are trying to make a USB Device code by referring to this DK2 example.

With regard,

Hi @Sudarshan 

I suggest performing a thorough debug to check errors during execution. Additionally, I noticed that the VDD core voltage differs in the schematics; please ensure that the power supply and related hardware implementation are correctly configured.
