When my device is removed, wavecyclic and the connection between wavecyclic and topology will be removed. The JackDescription.IsConnect in the topology Pin will be set to FALSE. In the control pannel, (OS: win7) I can see the device's status changed to unpluged/ disconnected. When right click the device, there is a CONNECT menu. How can I intercept exactly the CONNECT message? Thanks! Best regards. -- Danny
