Just updated to itunes 12.1.1.4 and now cannot see ipod touch
Running itunes under Windows 8.1 and having updated itunes to 12.1.1.4 I now cannot see my iPod Touch 4 running under 6.1.6. Tried all the full switch off routines and swapped cable for another spare. I get the beep from ipod and it charges but doesn't appear on itunes screen. Therefore synch impossible without it appearing. Tried my wife's iPad 3 running under latest 8.1.3. and get same result. Any ideas anyone??
iPod touch, iOS 6.1.6, 64GB
