DevCon Stack

  • Article

Note

PnPUtil ships with every release of Windows and makes use of the most reliable and secure APIs available. We recommend using PnPUtil instead of DevCon. See the Recommended replacement below and Replacing DevCon for more information.

Displays the expected driver stack for the specified devices, and the GUID and the name of the device setup class for each device.

devcon stack {* | ID [ID ...] | =class [ID [ID...]]}

Parameters

*

Represents all devices on the computer.

ID

Specifies all or part of a hardware ID, compatible ID, or device instance ID of a device. When specifying multiple IDs, type a space between each ID. IDs that include an ampersand character (&) must be enclosed in quotation marks.

The following special characters modify the ID parameter.

Character Description
* Matches any character or no character. Use the wildcard character (*) to create an ID pattern, for example, disk.
@ Indicates a device instance ID, for example, @ROOT\FTDISK\0000.
'(single quote) Matches the string literally (exactly as it appears). Precede a string with a single quote to indicate that an asterisk is part of the ID name and is not a wildcard character, for example, '*PNP0600, where *PNP0600 (including the asterisk) is the hardware ID.

=<class>

Specifies the device setup class of the devices. The equal sign (=) identifies the string as a class name. You can also specify hardware IDs, compatible IDs, device instance IDs, or ID patterns following the class name. Type a space between each ID or pattern. DevCon finds devices in the class that match the specified IDs.

pnputil /enum-devices /stack

Comments

The DevCon Stack operation displays the expected driver stack for a device. Although the actual driver stack typically matches the expected stack, variations are possible.

To investigate a device problem, compare the expected driver stack from the stack operation with the actual drivers that the device uses, as displayed by the DevCon DriverFiles operation.

Sample usage
