A user named Benxine found a fix that worked for me after failing with all the others:
IF your computer has an old cydia app called Wi-Fi Sync (you'll recognize it on your toolbar as a black silhouette of an iphone that NEVER goes away), then this is probably your main culprit. Simple fix.
1. Goto your hard drive in the finder
2. Goto Library
3. Goto Launch Daemons
4. Throw this in the trash: com.ghughes.wifisync.root.plist
5. Goto Library
6. Goto Application Support
7. Throw this in the trash: Wi-Fi Sync (it's an entire folder).
9. Thank Benxine!!

Only worked for me until I rebooted again...
While I don't have a solution as I too have tried everything. Those that did work only did so until I booted up again. However, I did make a discovery and that when I plug my IPhone directly into my MAC, I receive the error message in ITunes. But when I plug my IPhone into the USB port on my Audio Speaker which itself is plugging in the the MAC USB port, my IPhone 5 is seen and recognized by Itunes and syncs just fine.
It's not a fix unless you have an USB port expander, but its a clue to what's happening.
