DevCon HwIDs

Displays the hardware IDs, compatible IDs, and device instance IDs of devices on the system. Valid on local and remote computers.

devcon [/m:\\computer] hwids {* | ID [ID ...] | =class [ID [ID ...]]}

Parameters

/m:\\computer

Runs the command on the specified remote computer. The backslashes are required.

*

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

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.

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.

Comments

The /m parameter must precede the operation name (hwids). Otherwise, DevCon ignores the /m parameter and displays the hardware IDs of devices on the local computer without returning a syntax error.

To create a hardware ID for a root-enumerated device, use the DevCon SetHwID command.

Sample Usage

devcon hwids *
devcon /m:\\server01 hwids acpi* 
devcon hwids acpi* *port*
devcon hwids =usb
