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,

dobragab

  • Did you figure this out? I'm having the same issue. – George Mauer Jan 02 '15 at 03:43
  • 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](http://superuser.com/questions/305685/devcon-exe-not-working-in-windows7-x64) – George Mauer Jan 02 '15 at 03:46
  • 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. – dobragab Jan 02 '15 at 12:15
  • 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). – George Mauer Jan 02 '15 at 15:24

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. – clydde Feb 07 '16 at 15:16
