iTunes cannot see my devices over wifi. I have upgraded to the latest builds, i.e. OS X 10.10.2, iTunes 12.1.0.50, iOS 8.1.3.
This was also happening with earlier builds.
I have tried restarting (all devices, iTunes, mac mini, wifi network), removing devices from the wifi network, deleting old backups, renaming devices.
Any thoughts?
I have this problem also.
My iPad is connected directly to my iMac by usb cable.
Just updated iTunes to 12.1.0.50 and at first it could not find my iPad but it just stated "iPad" in devices - not the name I gave it originally.
Unaware of this problem I re-named my iPad and commenced Sync but its an ever syncing system and nothing further develops.
I have also powered off and re-started.
Now all I get is a popup saying it "cannot be synced because it cannot be found" and yet it shows up in the devices.
I've also just connected my iPhone directly to my iMac and whilst it shows in iTunes under devices cannot be synced because it too cannot be found.
Clearly Apple has a problem.

The solution, at least in my case, was to backup each device, restore each one, and finally restore the backup.
