I performed an Update of iTunes to 12.3 + XCODE to 7.0. Immediately after this update the Network unit of MBP stopped "see" the iPad connected via USB - there is no way to surf the Internet via this route: in the Networks window the iPAD is shown as "not connected". The Ipad still charges via USB and is visible in iTunes. I did reset of prefs on iPad as well as restarted both devices. Of course, the Hotspot is open and discoverable. I tried both USB ports. The cable is original and has not any damages. I assume the issue is within the last update. I still do not update to iOS9 though. Any ideas how to solve the issue would be highly appreciated.
