I'm just getting started with Android and a Mac, and installed HoRNDIS. It worked for tethering with no problem immediately.
Next I installed Android File Transfer on my Mac: http://www.android.com/filetransfer . Now the File Transfer dialog pops up and the network settings says my phone is not connected.
This is on a brand new Nexus 4 with Android 4.2.2 and Mac OS X 10.8.2.
I tried removing File Transfer and reinstalling HoRNDIS and it no longer can detect my Nexus.
Nevermind. I did not realize I needed to enable USB tethering on the phone each time I disconnected.
Oh, phew! I was about to go try to repro this here. I'll double check to make sure everything is OK later tonight, anyway. Thanks for the update.
<-- Android noob :)
Yeah, I can't repro the issue (however I did notice that Android File Transfer doesn't work while tethered). If anyone cares about the latter one, they can file a bug 😄
Either way, thanks for the note.
