CDC ECM on STM32U385RG

I would like to use USBX to make a CDC ECM USB device, but in STM32CubeMX, there is no option for CDC ECM or RNDIS in the USBX device class menu:

The STM32U545RE on the other hand has options for CDC ECM and RNDIS:

Does STM32U385 support CDC ECM and RNDIS with USBX? If yes, is there something I need to do in order to show CDC ECM as an option in STM32CubeMX?

Thanks!

Hello @wmcgsandc and welcome to the community,

The middlewares of STM32CubeU3 firmware supports CDC ECM and RNDIS with USBX.

I reported this issue internally to STM32CubeMX team for checking and fixing.

Internal ticket number: 216534 (This is an internal tracking number and is not accessible or usable by customers).

Thank you.
