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!
