I'm having problems with iPad tethered USB internet share (personal hotspot). OS X 10.11. (15A226f) and iOS 9b (13A4325c)
Tethering via USB to iPads internet has worked before, but as far as I remember it stopped working after updating OS X to 10.11., so most likely the problem is NOT iOS 9, but the OS X 10.11
I'v already tried rebooting both devices, reconnecting everything etc., but nothing seems to work.
