From: Brausewetter, Kurt on 9 Sep 2010 11:11 Hi I work on a Device Upper Filter (WDK: Toaster) I'm in the FilterAddDevice function and Enum the DeviceInterfaces with IoGetDeviceInterfaces Now my question: How can i dublicate an DeviceInterface (in the same or an other InterfaceClassGuid) with all Node/Pin Propertys/Data/... The Interface is in its Driver with KsInitializeDriver or BdaXxxXxx generated. CU Brause

I think you are confused. Device interface are just used to find drivers. They don't have anything to do with functionality. Unfortunately, the word "interface" has several conflicting meanings in the driver world. All of the kernel streaming APIs are implemented through ioctls. Why do you want to duplicate them? As a filter driver, you can just pass through the ones you don't want to handle. -- Tim Roberts, timr(a)probo.com Providenza & Boekelheide, Inc.
From: Brausewetter, Kurt on 11 Sep 2010 13:02 Thanks for Answer! No i'm not confused! Why will i dublicate it (DeviceInterface) I have a proprietary Software that use only it's own Interfaces (FriendlyName). So i will it not Rename (The (SDK from the NEW Card have Problems with this way) When i have an Intervce with the orginal FriendlyName and one with the proprietary FriendlyName.

OK I'm confused: The words prove it ;-) What want I to get: I need 2 DeviceInterfaces (absolutely identical, to same PDO) with different FriendlyName AddDevice is not the right place. I have already learned from MSDN: The DispatchPnp IRP_MN_START_DEVICE is better because I also has to react to IRP_MN_REMOVE_DEVICE and others to start and stop etc. But how can I Duplicate the Interface?
