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.

Useful information, but pretty useless if you just want to get hold of a small simple tool for just one task (devcon.exe x64).  Why is it so difficult to get at these things?!

Answer 4

Hi,

Could you put this utility somewhere for others to download?  There seem to be quite a few people experiencing the issue where Windows 7 creates hundred of '6to4' adapters.  I can't believe it's not easier to get the tools to deal with this problem, especially as Microsoft reps are here and could provide the links to just the required tool to get rid of all the entries.

Answer 5

I have no idea, no... maybe you need a newer version of VS to compile. But, why'd you wanna do that? devcon comes as a ready-to-run exe...
