PRB: Passing DeviceObject to HalAssignSlotResources Is Mandatory

HalAssignSlotResources returns STATUS_INVALID_PARAMETER_3 if the DeviceObject parameter is NULL.

HalAssignSlotResources is obsolete and is exported only to support existing drivers. Drivers of Plug and Play (PnP) devices are assigned resources by the PnP Manager, which passes resource lists with each IRP_MN_START_DEVICE request.

On a computer running Windows 2000, all the bus-related hardware abstraction layer (HAL) functions are patched to call the actual bus driver. Because the bus driver tracks resources on a PDO basis, the system needs a device object to simulate (fake) a PDO.

You must specify a device object when you use HalAssignSlotResources.

This behavior is by design.
