RNDIS didn't work on Ubuntu for me (maybe need to find a driver), but CDC-ECM is the right protocol for Linux I think.
My wish is to get RNDIS and CDC-ECM enabled (as a composite device I think) so users have no need to download or install drivers for Windows or Linux. Mac probably needs something installed away from the dreaded Apple Store but that is usual! Arp failing is a pretty fundamental problem! On 26/01/2023, 19:47, "Alan C.

So it will requires some investigation to understand what is going on. Try to use it connected to some Linux machine to confirm.
