Virtual comm port is not being formed in USB_CDC project.

[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 are also copied from the example project. Both, example project and My project, look same. My project builds also successfully. But no COMM port is being formed after loading the project to STM32U5G-DK2 whereas, COMM port is being formed with Example project.

What could be the reason ? Please help.

With regard,

Does the example project work?

Did you do a diff between projects to see what is different?
