DEVICE_REGISTRY_PROPERTY enumeration

Description

The DEVICE_REGISTRY_PROPERTY enumeration identifies device properties that are stored in the registry.

Constants

DevicePropertyDeviceDescription

String describing the device, such as "Microsoft PS/2 Port Mouse", typically defined by the manufacturer. Property type is a NULL-terminated WCHAR string.

DevicePropertyHardwareID

Hardware IDs provided by the device that identify the device. Property type is a REG_MULTI_SZ value.

DevicePropertyCompatibleIDs

Compatible IDs reported by the device. Property type is a REG_MULTI_SZ value.

DevicePropertyBootConfiguration

Hardware resources assigned to the device by the firmware, in raw form. Property type is a CM_RESOURCE_LIST structure.

DevicePropertyBootConfigurationTranslated

The hardware resources assigned to the device by the firmware, in translated form. Property type is a CM_RESOURCE_LIST structure.

DevicePropertyClassName

Name of the device's setup class, in text format. Property type is a NULL-terminated WCHAR string.

DevicePropertyClassGuid

GUID for the device's setup class. Property type is a NULL-terminated array of WCHAR.

The GUID in a string format as follows, where each "c" represents a hexadecimal character: {cccccccc-cccc-cccc-cccc-cccccccccccc}

DevicePropertyDriverKeyName

Name of the driver-specific registry key. Property type is a NULL-terminated WCHAR string.

DevicePropertyManufacturer

String identifying the manufacturer of the device. Property type is a NULL-terminated WCHAR string.

DevicePropertyFriendlyName

String that can be used to distinguish between two similar devices, typically defined by the class installer. Property type is a NULL-terminated WCHAR string.

DevicePropertyLocationInformation

Information about the device's location on the bus; the interpretation of this information is bus-specific. Property type is a NULL-terminated WCHAR string.

DevicePropertyPhysicalDeviceObjectName

Name of the PDO for this device. Property type is a NULL-terminated WCHAR string.

DevicePropertyBusTypeGuid

GUID for the bus that the device is connected to. The system-defined bus type GUIDs are listed in the Wdmguid.h header file. Property type is a GUID, which is a 16-byte structure that contains the GUID in binary form.

DevicePropertyLegacyBusType

Requests the bus type, such as PCIBus or PCMCIABus. Property type is an INTERFACE_TYPE enumeration value.

DevicePropertyBusNumber

Legacy bus number of the bus the device is connected to. Property type is a ULONG.

DevicePropertyEnumeratorName

Name of the enumerator for the device, such as "PCI" or "root". Property type is a NULL-terminated WCHAR string.

DevicePropertyAddress

Address of the device on the bus. Property type is a ULONG.

The interpretation of this address is bus-specific. The caller of this routine should call the routine again to request the DevicePropertyBusTypeGuid, or possibly the DevicePropertyLegacyBusType, so it can interpret the address. An address value of 0xFFFFFFFF indicates that the underlying bus driver did not supply a bus address for the device.

See Remarks for additional bus driver-specific information.

DevicePropertyUINumber

Number associated with the device that can be displayed in the user interface. Property type is a ULONG value.

This number is typically a user-perceived slot number, such as a number printed next to the slot on the board, or some other number that makes locating the physical device easier for the user. If the device is on a bus that has no UI number convention, or if the bus driver for the device can't determine the UI number, this value is 0xFFFFFFFF.

DevicePropertyInstallState

Device's installation state. Property type is a DEVICE_INSTALL_STATE enumeration value.

DevicePropertyRemovalPolicy

Device's current removal policy. The operating system uses this value as a hint to determine how the device is normally removed. Property type is a DEVICE_REMOVAL_POLICY enumeration value.

DevicePropertyResourceRequirements

Device's resource requirements. Property type is an IO_RESOURCE_REQUIREMENTS_LIST structure.

DevicePropertyAllocatedResources

Device's allocated resources. Property type is a CM_RESOURCE_LIST structure.

DevicePropertyContainerID

Device's container ID. Property type is a NULL-terminated WCHAR string.

Remarks

For the DevicePropertyAddress value, the following list describes the information that certain bus drivers store for their child devices:
