Hello! Where can I find an EXACT information about MediaCategories naming support in Vista? I need to create several Wave/Topology subdevices in my filter. I understand that Vista constructs endpoint device names differently than 2k/XP but I cannot fully understand Vista's behavior. First, I cannot get KSPROPERTY_GENERAL_COMPONENTID to work in Vista. It works perfectly in XP, it is queried in Vista but I can't see any effect. I see in my logs that my property request handler is invoked, it fills the KSCOMPONENTID descriptor, IRP is competed successfully by portcls but there is no place where I could see my custom names. All MediaCategories GUIDs are set, of course. Second, I cannot get all of my topology subdevices to produce my custom names for the endpoints. I have two source bridge pins: microphone (KSNODETYPE_MICROPHONE) and line (KSNODETYPE_LINE_CONNECTOR). I specify my custom GUIDs in the Name fields of the KSPIN_DESCRIPTOR, but I see VERY strange results. After installation, some endpoints are created using my custom names, but other still have the "Microphone" and "Line In" prefixes. If I reinstall the driver, deleting .inf and .pnf files and/or reboot Vista, I see some names changed, but not all. I even seen some of my endpoints disappeared at all. Of course, I didn't change any code except related to the name GUIDs. Seems like Vista keeps these names in its proprietary storage and doesn't reload from MediaCategories even the driver is reinstalled. Is there a WORKING example of the driver that names its endpoint devices as it wants? I use Vista RC2 (5744), all automatically downloadable updates are installed. Maybe I need to upgrade it to more recent version?
