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. The following list describes the information certain bus drivers store for their child devices:	Bus	Description		-----	-------------		1394	Does not supply an address because the addresses are volatile. Defaults to 0xFFFFFFFF.		EISA	Slot Number (0-F).		IDE	For an IDE device, the address contains the target ID and LUN. For an IDE channel, the address is zero or one (0 = primary channel and 1 = secondary channel).		ISApnp	Does not supply an address. Defaults to 0xFFFFFFFF.		PC Card (PCMCIA)	The socket number (typically 0x00 or 0x40).		PCI	The device number in the high word and the function number in the low word.		SCSI	The target ID.		USB	The port number.
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 cannot 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.

DevicePropertyAllocatedResources
