STM32H573 USBX CDC ACM(DEVICE)

[Eakyo.1]

Hello,

I am working on device USBX cdc acm with stm32h573i-dk. I am progressing my work from the example in the attachment below.

After creating the project as in this example, I ran the software and no Com Port appeared on my computer. Also no error_handler is generated and scheduler is working correctly.

I am waiting for your help on where the error is.

Best Regards.

Hello @KDJEM.1 ,

unfortunately, it looks as if it has only been partially fixed. If the Code Generator is set to "Generate peripheral initialization as a pair of '.c/'h' files per peripheral", calling "HAL_PWREx_EnableVddUSB()" during init is still missing when using the latest STM32CubeMX (6.12.1-RC4).

Hello @sebreit ,

This issue is already reported in this post Missing HAL_PWREx_EnableVddUSB when generating peripheral initialization as a pair of '.c/.h' files .

It will be fixed in the coming release.

I apologize for any inconvenience and thank you for your contribution in STCommunity.
