Implementation of Ethernet over USB on STM32L072CZY3TR

Associate II

Dear Team,

I hope this email finds you well. I am reaching out to discuss a technical challenge we are facing with the STM32L072CZY3TR microcontroller. Our goal is to implement Ethernet over USB functionality.


From my research, I understand that the CDC-RNDIS or CDC-ECM protocol can be used to carry Ethernet frames over USB, creating a virtual network connection.

so, for that I used the stack from STM32 GitHub repository. "GitHub - STMicroelectronics/stm32_mw_usb_device at 2022e75b01a499b17acd17d28691b1ed5bbef2dc"

but I landed with an issue where USB port is detecting network adaptor in device manger but disabled in network sharing options.



so please suggest some other approach to meet the ethernet over USB functionality or how to clear the issue.


thanks in advance,

R.sai sankar rao.
