Apple - High CPU usage by a process called PTPCamera

So we found the Solution:

1. Connect your iPhone/Camera and reopen Photos.app or iPhoto
2. Close iPhoto or Photos.app
3. Disconnect your iPhone/Camera
4. Open Photos/iPhoto again

now the PTPCamera Process should be terminated gracefully and won't spawn again in a busy waiting loop.

You do not have to do this steps all the time, only necessary to terminate the process graceful and kick it out of the busy waiting state. How to come in this state, we (AppleDev and I) do not know.
