Q: Devcon not working correctly in Windows 7

*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 !

A:

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.
