https://devzone.nordicsemi.com/f/nordic-q-a/86985/nrf52-usb-cdc-ecmIn searching, I haven&#39;t been able to find much information on implementing USB CDC ECM. Has anyone successfully implemented CDC-ECM with an nRF52? Alternatively, has anyone had success with libraries such as tinyusb for implementation of CDC-ECM?en-USTelligent Community 13Tue, 19 Apr 2022 12:02:38 GMThttps://devzone.nordicsemi.com/thread/363560?ContentTypeID=1Tue, 19 Apr 2022 12:02:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:442e2520-09ec-45fc-a6c0-0536229b1c75Sigurd Hellesvik<p>Hi</p> <p>&quot;USB CDC ECM&quot; is listed as supported in the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.9.1/zephyr/reference/usb/uds.html">Zephyr USB device stack</a>.</p> <p>While not any ECM samples, you could possibly get some inspiration on how to use the Zephyr USB device stack from the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.9.1/zephyr/samples/subsys/usb/usb.html">USB device support samples</a>.</p> <p>Regards,<br />Sigurd Hellesvik</p><div style="clear:both;"></div>
