DevCon Resources

Lists the resources allocated to the specified devices. Resources are assignable and addressable bus paths, such as DMA channels, I/O ports, IRQ, and memory addresses. Valid on local and remote computers.


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

   

Parameters

/m:\\computer

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

Note   To run DevCon commands on a remote computer, the Group Policy setting must allow the Plug and Play service to run on the remote computer. On computers that run Windows Vista and later versions of Windows, the Group Policy disables remote access to the service by default.
*

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.

CharacterDescription

*

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.

Comments

The /m parameter must precede the operation name (resources). Otherwise, DevCon ignores the /m parameter and displays the resources allocated to devices on the local computer without returning a syntax error.

Sample Usage


devcon resources *
devcon /m:\\server01 resources =media
devcon resources acpi* *port*
devcon resources =class port* (by class and hardware ID)
devcon resources =class @port*(by class and device instance ID)

Examples

Example 12: List resources of a class of devices

Example 13: List resources of device on a remote computer by ID
