Windows Phone cannot be detected by Zune

If this happens and Device Manager shows:

"Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. To fix this problem you can first try running a Troubleshooting Wizard. If that does not work, you should uninstall and then reinstall the hardware device. (Code 19)"

one can uninstall the driver for the device, then scan for new devices to reinstall the driver and populate the registry properly.
