Today I'm thankful for ...

... trying to reinstall iTunes. After doing the Leopard upgrade I noticed the iPhone was not syncing at all. The System Profiler did show the device as being connected, but then looking in the Console log I was seeing:

Jul 7 00:03:48 Xxxxxx [0x0-0x1e01e].com.apple.iTunes[195]: USBMuxListenerCreate: No such file or directory

I searched around for "USBMuxListenerCreate" problems and almost nowhere did I see an appropriate solution. I was just about to give up right now when I decided to try to download iTunes again. And, what do you know? It worked! No problems syncing anymore.
