Description

The Get-PnpDeviceProperty cmdlet gets detailed properties for a Plug and Play (PnP) device. You can specify a device by instance ID or by using the Get-PnpDevice cmdlet.

A device property is a key-value pair. A property key takes the form {GUID} PID. The property value is one of several types, such as UTF-8, GUID, Uint32, or Boolean. The output object contains the typed data of a value, and the value type. Many properties also have friendly names, in the form of DEVPKEY_XXX.

Examples

Example 1: Get properties for a device by using an ID

PS C:\>Get-PnpDeviceProperty -InstanceId 'SWD\PRINTENUM\{E82E5EFD-6616-4E4F-9A96-7D94554A8BF0}'
InstanceId KeyName                                   Type       Data

SWD\PRI... DEVPKEY_Device_CompatibleIds              StringList {GenPrintQueue, SWD\GenericRaw, SWD\Generic}               
SWD\PRI... DEVPKEY_Device_Class                      String     PrintQueue                                                 
SWD\PRI... DEVPKEY_Device_ClassGuid                  Guid       {1ED2BBF9-11F0-4084-B21F-AD83A8E6DCDC}                     
. . .

This command uses the Get-PnpDevice cmdlet to get the PnP device that has the specified ID. The command passes that object to the current cmdlet by using the pipeline operator. The current command gets the device properties for that device.

Example 3: Get properties by using GUID-ID pairs

Inputs

CimInstance[]

The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

Outputs

System.Int32, Win32_PnPDeviceProperty[]

This cmdlet generates an Int32 WMI success or failure code, or an array of Win32_PnPDeviceProperty objects that represent properties for a PnP device. A Win32_PnPDeviceProperty object contains the following fields:

  • Device. The instance ID for the device with which this property is associated.
  • KeyName. The friendly name for the property. If no friendly name exists, this matches the Key field.
  • Key. The unique [GUID]-ID pairing representing the property.
  • Data. The typed data associated with the key. This value is defined in the classes which inherit from Win32_PnPDeviceProperty. For example, a Win32PnPDevicePropertySint32 object would be returned for an Int32 property. Data would be an Int32 value in this case.
  • Type. The type of the binary data. This is defined in the PnpDeviceProperty.Type enum.

Notes

  • The objects returned by Get-PnpDeviceProperty are all of the (WMI Object) Win32_PnPDeviceProperty type. They are always of a WMI class inherited from Win32_PnPDeviceProperty. For example, a device may contain a String and signed Int32 properties. The cmdlet returns a Win32_PnPDeviceProperty array, where the first object in the array is a Win32_PnPDevicePropertyString object and the second is a Win32_PnPDevicePropertySint32 object. For each object type, there is a Data variable, of the given type, which contains the value of the property.

    The following is a full list of possible WMI classes and the type of the Data variable:

  • Win32_PnPDevicePropertyUint8. Uint8.

  • Win32_PnPDevicePropertyUint16. Uint16.

  • Win32_PnPDevicePropertyUint32. Uint32.
