STM32U575VIT6Q - USB CDC not enumerating

[velmuruganbel]

Hi All,

 

We ran the example application code on our board with STM32U575VIT6Q and the USB CDC is not enumerating,
whereas USB DFU mode is working when we trigger the boot0 button while powering on or resetting the device

https://github.com/STMicroelectronics/STM32CubeU5/tree/main/Projects/NUCLEO-U575ZI-Q/Applications/USBX/Ux_Device_CDC_ACM

Note: Code is executing without any errors, but still it is not enumerating on the PCB.

Any idea what could be the reason?
