What’s NDIS and what do you mean to run it in userspace? I am very new to Linux and am barely considered tech savvy so this is all going over my head

I just googled what a NDIS is and with my limited knowledge I think I understood what you’re saying. Are you saying that I could keep an older/custom version of NDIS running on my own user account instead of changing the entire kernel for me to be able to use USB CDC NCM to keep using USB tethering?

So if my mint install updates I won’t be able to use USB tethering? Is there a way to update my phone to use USB CDC NCM? Or would I have better luck recompiling my mint install to add the standard they just removed? I’m pretty new to Linux (literally made the switch last November) and I sadly have to use USB tethering when my ISP shits the bed with routing to the US

Aren’t you literally more likely to win the lotto them to be in an airplane crash?
