Devcon disable not working in Windows 8.1

Question

I'm trying to make a simple script that disables my touchpad fast. I found tons of articles about devcon, I downloaded it, and I always get an error as I'm trying to do it, no matter which version of devcon I'm using.

C:\Windows\system32>devcon disable ACPI\ETD0108
ACPI\ETD0108\4&30E2CFCB&0                                   : Disable failed
No devices disabled.

I'm using Windows 8.1. Has anyone faced the same problem, or knows the solution?

Edit: I've tried to disable my USB mouse, with success. Then why is it a problem only of my touchpad?

Thanks,

Did you figure this out? I'm having the same issue. – Passel

I will point out that it seems like you might be using the 32 bit version on a 64 bit system. I've seen notes online that this will have limited functionality, not always letting you disable/enable things. To get the 64 bit version you will have to get it as noted here – Passel

Yes I found that thread, I can assure you that I use the correct version. (I can disable everything else with devcon, except touchpad.) I guess it just cant be disabled, because it is also impossible to disable from Device Manager. Original Asus keyboard and touchpad drivers had the hotkey to disable it, but I replaced that topchpad driver with Elantech driver, because the old one is crap. With new driver the hotkey isnt working. I have no idea if the old driver made it impossible to disable for other devices, or it is completely impossible. Anyway, I gave up. – Ozone

Yeah.. I'm on an HP Envy but same exact story. I can't get the right version working either (though with a different error than yours). I even tried the [DeviceManagement powershell](Error calling SetupDiCallClassInstaller) module to no luck (getting Error calling SetupDiCallClassInstaller when trying to disable). – Passel

Answer 1

You need to comment out the "&" try using ^& also only use the longer line

C:\Windows\system32>devcon disable ACPI\ETD0108\4^&30E2CFCB&0

You need the devcon.exe for windows 8.1
Windows Device Console (Devcon.exe) which can be downloaded from Download the Windows ADK

After install all WDC, locate yhe devcon.exe in your Kit folder and copy into system32 folder. You uninstall all package and devco works perfectly. – Balduin
