New version of itunes came out this week. Do you have the latest? What about the phone. Running ios 8.4?
Sorry, I don’t know. Have you talked to Apple?
I cannot help your current problem, but I side-stepped iTunes altogether because I never liked iTunes - for an Apple product, it does not seem all that user-friendly.
I wanted a simple way to directly upload MP3 files to my iPhone and found an app in the iTunes store for a couple bucks that does the trick. It is called “Downloads - Downloader & Download Manager”. It combines a browser, media player and simple file manager. I can plug the iPhone’s USB/Power cable into the USB port on a Windows/Mac/Linux computer and make direct transfers of music, pictures, and video to Downloads folders, using the computer’s own file manager instead of iTunes. WiFi transfers are also possible. I can access and play those media directly within the Downloads program.

Are you using the apple cord, or a replacement one. I know with my ham radios if you don’t use the “exact” cord, your computer wouldn’t ever see the radio.
Just a thought.
Itunes is malware, IMHO.
Uninstall iTunes, restart the pc then download a new copy and install. We get calls on this on occasion at work. See list of programs below you have to uninstall.

Apple Application Support (iTunes 9 or later). On some systems, iTunes might install two versions of Apple Application Support. This is expected. If both are present, be sure to uninstall both versions.
Don’t uninstall these components in a different order, or only uninstall some of them. Doing so might have unintended effects.
