Default Behavior

The Software Bus Driver service is a kernel device driver. In Windows 8 it will not be started until the user starts it. If Software Bus Driver fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the swenum service hasn't been started.
