How about SdBusOpenInterface() failed

How about SdBusOpenInterface()

I call it in my MiniportInitialize() function, but it failed.


  NdisMGetDeviceProperty(
   Adapter->MrvDrvAdapterHdl,
   &(Adapter->PhyDeviceObject),
   &(Adapter->FuncDeviceObject),
   &(Adapter->LowerDeviceObject),
   NULL,
   NULL
   );
        KdPrint((\"NdisMGetDeviceProperty()   Adapter = %x,\\nPDO = %x,\\n FDO
= %x,\\n LDO = %x\\n\",Adapter->MrvDrvAdapterHdl,
   Adapter->PhyDeviceObject,Adapter->FuncDeviceObject,Adapter->LowerDeviceObject));

        //Open Sd
  Status = SdBusOpenInterface(
     Adapter->LowerDeviceObject,//UnderlyingPDO
     &Adapter->SdBusIfStd,
     sizeof(SDBUS_INTERFACE_STANDARD),
     SDBUS_INTERFACE_VERSION);


where should I modify? thanks!
