The WIA_DPS_GLOBAL_IDENTITY property contains the SOAP address of a web services scanner device. The WIA minidriver creates and maintains this property.
Property Type: VT_BSTR
Valid Values: WIA_PROP_NONE
Access Rights: Read-only
The WIA minidriver initializes this property at run time by reading the PKEY_PNPX_GlobalIdentity device property from the Function Instance object.
Both PKEY_PNPX_GlobalIdentity and PKEY_PNPX_ID contain a unique ID of the UPnP Device. The difference is that PKEY_PNPX_GlobalIdentity always contains the UUID of the root device for all Function Instances, while PKEY_PNPX_ID contains the UUID of the Device/Sub-Device that the Function Instance represents.
