How to read the Location information using setupdicalls

Hey,

I have a problem in getting the location information using the setupdigetregistryproperty call.
code snipet:
SetupDiGetDeviceRegistryProperty( ppd->DeviceInfoSet,
ppd->DeviceInfoData,
SPDRP_LOCATION_INFORMATION,
NULL,
szValue,
MAX_PATH, NULL) )

This function succeeds in w2k3 x86 Operating system, Because the property page of my controller has the location information in under the “Details tab”. But the same does not work for w2k3 x64 OS, wherein the location information is not displayed inthe “Details tab” of the controller.

I have no clues about who writes these information in the “details tab” of the controller’s property page".

Is there any other way of getting the location information of the controller?

Regards,
Karthik.
