I don't have a Pi to test with but I imagine keeping the associated kernel module(s) (assuming I have the right ones) unloaded would mitigate this entirely: kextunload /System/Library/Extensions/AppleUSBEthernet.kext and maybe this one. I don't know if this would impact using your phone as a usb hotspot but it might so keep that in mind: kextunload /System/Library/Extensions/AppleUSBNetworking.kext and this one but I'm pretty sure it is in fact required for usb tethering so keep that in mind if you use that: kextunload /System/Library/Extensions/AppleUSBEthernetHost.kext I don't remember if they reload on reboot or not but if needed you can reload them with kextload. Edit: This is for OS X/macOS by the way. And I wish I had a Pi to test with because this is very cool. We owe people that release stuff like this a big thanks because they took it from an idea to implementation and then the big step of creating a usable, shareable project which goes a long way toward increasing awareness.
