Windows cannot start this hardware device. (Code 19)

A registry problem was detected.

This can occur when more than one service is defined for a device, if there is a failure opening the service subkey, or if the driver name cannot be obtained from the service subkey. Try these options:

On the General Properties tab of the device, click Troubleshoot to start the Troubleshooting Wizard. Click Uninstall, and then click Scan for hardware changes to load a usable driver. Restart the computer in Safe Mode, and then select Last Known Good Configuration. This rolls back to the most recent successful registry configuration.
