Devcon not working correctly in Windows 7

Question

*original title - Command Prompt pop-ups with DevCon"

Hi everyone,

My problem is :

I use Devcon to manage my devices, it's a small .exe file.

With the command : devcon /hwids, the program returns all the devices linked with the PC.

But when I do this, it open a new window, print the list, and then this window close.

But what should normally happened, and what I want, is that the list print in the same window I execute the command.

With the aim, after, to write this list in a txt file, with the command : devcon /hwids *usb* > device.txt

Thank You !

OK, I've now managed to use devcon.exe to disable/enable my WiFi adapter. Here's what I did.

1. I DL'ed the “Windows Driver Kit (WDK) 7.1.0″ from MS, it is an ISO image several hundreds meg
2. Using UniversalExtractor (http://legroom.net/software/uniextract) I extracted the ISO to a temporary folder on my HD
3. Again using UniversalExtractor, I extracted the install file "WDK\setuptools_x64fre.msi" to a temporary dir
4. In that temporary dir you will find "WinDDK\7600.16385.win7_wdk.100208-1538\tools\devcon\amd64\devcon.exe". This devcon works fine (as far as I've tested) for me under W7x64 Pro.

Along the way UniversalExtractor will prompt you with some warnings, just click OK.

*phew* so much time wasted for such a simple thing...

Note: devcon MUST be run from an administrator cmd win.

Answer 3

I had the exact same problem, and what was even more confusing is that I had two different win7 machines where one was working as expected and the other behaving according to your description.

It turned out (after the helpful comments here) that when i press Win+R on the computer where it was working there is a warning that "This task will be created with administrative privileges" while on the computer it wasn't working this warning was missing.

One more difference: when I ran the devcon.exe in a cmd window i started on the non-working computer I got a question to allow the application to run with administrative rights, after which the command opened in a new window which was shut immediately after it finished, exactly as you describe it.

On the non-working computer I had to start the cmd window by searching for cmd.exe in the start menu, right click on the link and select "Run as administrator" to get the devcon.exe to run correctly in my command window.

Will only last 7 days apparently.  This will do till I find a better place - recommendations?
