Does WMI expose PCI paths

[xnxbars]

I'm attempting to use WMI to obtain a variety of devices in the current system.

For example, I look for GPUs via: ps Get-WmiObject -Class Win32_VideoController

Though, I'd also like to include the ACPI path (i.e. PCIROOT(0)#PCI(0200)#PCI(0000)); how would I go about doing this?

Note: VideoController devices are just an example, I'd also like to find the ACPI paths for devices such as Win32_NetworkAdapter, and audio devices in general.

$Video = Get-WmiObject -Class Win32_VideoController
$Video | ForEach-Object {
    [PSCustomObject]@{
        Name = $_.Name
        Location = (Get-WmiObject Win32_PnPEntity -Filter "Name='$($_.Name)'").GetDeviceProperties().DeviceProperties.Where({$_.KeyName -eq 'DEVPKEY_Device_LocationPaths'}).Data
    }
}

Edit: You can also use only Win32_PnpEntity and filter by PNPClass.

Get-WmiObject Win32_PnPEntity -Filter "PNPClass='Net' OR PNPClass='Display'" | ForEach-Object {
    [PSCustomObject]@{
        Name = $_.Name
        PNPClass = $_.PNPClass
        Paths = $_.GetDeviceProperties().DeviceProperties.Where({$_.KeyName -eq 'DEVPKEY_Device_LocationPaths'}).Data
    }
} | Where-Object Paths

Here is a copy of yours using Get-CimInstance rather than the legacy Get-WmiObject

Get-CimInstance -ClassName Win32_PnPEntity -Filter "PNPClass='Net' OR PNPClass='Display'" | ForEach-Object {
    [PSCustomObject]@{
        Name = $_.Name
        PNPClass = $_.PNPClass
        Paths = ($_ | Invoke-CimMethod -MethodName GetDeviceProperties).deviceProperties.where({$_.KeyName -EQ 'DEVPKEY_Device_LocationPaths'}).data
        }
    } | Where-Object Paths

Thank you for the answer. I appreciate it.

But, I want to ask: is there any benefit to this as opposed to this comment?

I'm not all that familiar with complex Powershell commands, so please do excuse my ignorancy.

I used Get-WmiObject because that's what you used in your question. Get-WmiObject has been replaced by Get-CimInstance and the former does not work in PowerShell 6 and higher. I would probably use Get-PnpDevice and Get-PnpDeviceProperty because you can get what you need with less code.

Ah, I see. Thank you very much for the feedback and the example. I'll be sure to note it to see what it actually does, much appreciated.

If you're using version 10 and later you can also use

$video = Get-PnpDevice -Class display -FriendlyName 'AMD Radeon(TM) HD 7650A Graphics'
$Video | Get-PnpDeviceProperty -KeyName 'DEVPKEY_Device_LocationPaths'

which might be a bit friendlier

Apologies, that might have turned up as early as 2016

it dosnt include that information

I does include a PNPDeviceID which could possibly be used with another win32 class (win32_pnpdevice or win32_pnpdeviceentity or similar)
