Retrieving Device Setup Information

To retrieve setup information from the registry, an adapter driver can call the PcGetDeviceProperty function, and a miniport driver can call the port driver's IPort::GetDeviceProperty method.

For either of these calls, the caller selects the type of setup information to request by setting the device-property parameter to one of the following DEVICE_REGISTRY_PROPERTY enumeration values from header file Wdm.h:

• DevicePropertyAddress

• DevicePropertyBootConfiguration

• DevicePropertyBootConfigurationTranslated

• DevicePropertyBusNumber

• DevicePropertyBusTypeGuid

• DevicePropertyClassGuid

• DevicePropertyClassName

• DevicePropertyCompatibleIDs

• DevicePropertyDetachability

• DevicePropertyDeviceDescription

• DevicePropertyDriverKeyName

• DevicePropertyEnumeratorName

• DevicePropertyFriendlyName

• DevicePropertyHardwareID

• DevicePropertyInstallState

• DevicePropertyLegacyBusType

• DevicePropertyLocationInformation

• DevicePropertyManufacturer

• DevicePropertyPhysicalDeviceObjectName

• DevicePropertyUINumber

For a description of the DevicePropertyXxx values above, see IoGetDeviceProperty.
