To see if the Twain Data Source Manager itself is working with at least one data source, you can use the Leadtools.Twain.TwainSession.IsAvailable() method.
If you want to check a specific data source (Twain Driver) in a Twain session, use the CAP_DEVICEONLINE capability (TwainCapabilityType.DeviceOnline).
