DevCon Resources
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.
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.
devcon resources {* | 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.
Recommended replacement
pnputil /enum-devices /resources
