@Alex_h1. I have the same problem and the steps you outline did not resolve them. I'm still looking.

I have two Macs and three devices. Neither mac can recognize any device.

10.10.x and 8.1.2

It seems to me you have two problems. The battery charging and the connection to iTunes..

Re the first, it sounds like you need a new battery. They are fairly easy to replace oneself, but if there is a local shop that can do it, so much the better.

Re connecting to iTunes, I found two solutions on Apple Support Communities. Apple's solution is first. That didn't work for me. The second method worked for me on two computers and three devices. And no side effects so far, i.e. Time Machine is fine. It is not Apple's recommended method.

Apple solution:

1.1 Terminal: defaults delete com.apple.SyncServer SyncServicesResetWorldRunOnce

1.2 Reboot your computer.

1.3 Unplug and reconnect your device(s)See this link for the article

Hatchet solution

2.1. Go to ~/Library/ApplicationSupport

2.2. Find the folder SyncServices

2.3. Delete it.

2.4. Reboot your computer

2.5. Unplug and reconnect your iOS device(s).
