I get the same thing and iTunes won't start when I connect to the front USB hub. I get a phantom Dadunk without my iPhone being plugged in at all. Weird.

Check your drivers... also try starting iTunes manually. I think there is a setting that allows you to connect without bringing up iTunes which is probably what is happening if you hear the dading.
