is there a way how to enumerate device interfaces registered for certain physical device object (PDO)? By the term "device interface" I mean the thing registreded through IoRegisterDeviceInterface routine and (de)activated via IoSetDeviceInterfaceState one.

AFAIR the SetupAPI won't help me. I need to enumerate all interfaces registered for certain PDO. I looked at some interface enumeration functions and they usually require to specify the interface GUID which is exactly what I need to find (so I cannot specify it).

IoRegisterDeviceInterface creates Symlink, so why not enumerate them?

Thanks. Enumerating the symbolic links will be probably enough for me. Especially if the interface GUID is part of the symlink's name (which seeems it might be).
