Could My OS Possible Be Preventing my iPhone From Connecting via USB?

    I'm trying to connect an iPhone to a Mac Mini via USB. The cable is known to be good. The USB ports all work with other USB devices. The iPhone works with USB devices on other computers AND if I plug it directly into the wall.

    HERE'S the crazy part. When restart the computer with the iPhone plugged in, it CONNECTS while the OS is not in the ROM. As soon, however, as the OS starts to boot again, the iPhone disconnects.

    Let me say that more clearly.

    I plug the iPhone in and nothing happens, including not indicating that it's charging (this is the problem).

    With the iPhone still plugged in, I restart the Mac.

    After all the open applications quit and the finder disappears, the iPhone chirps indicating that it's connected and charging.

    It STAYS charging while the Mac cycles through the rest of the restart.

    When, however, the Mac gets to the point where it starts booting the OS, the iPhone chirps again indicating that it's been disconnected.

    Crazy, right?

    I would try re-installing iTunes - it sounds like a driver issue with recognizing it as a iPod device versus a USB storage device.
