    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?

    Try reinstalling iTunes. And if that doesn't work you may need to totally uninstall iTunes and reinstall.

    I'm having a similar issue. I noticed it when I installed the new iTunes 9. Is this an iTunes issue?

    My phone will charge with a charger, just won't charge when connected to the computer and will not show up in iTunes as a device. Other devices work in the usb ports, so I don't think its an onboard usb issue.

    Any thoughts?????

    Sounds like your driver is corrupt or missing. I'd try a reinstall of iTunes.
