The DevCon utility is a command-line utility that acts as an alternative to Device Manager. Using DevCon, you can enable, disable, restart, update, remove, and query individual devices or groups of devices. DevCon also provides information that is relevant to the driver developer and is not available in Device Manager.

DevCon will erase all of your USB device drivers, making your PC just like new. Then it will scan to relocate the devices and reinstall their drivers. So in case any of your USB decives shows problems or cannot find drivers needed, then its best to run this utility.

A detailed tutorial on how to use DevCon and the commands to be used are available here. DevCon is a Microsoft product. Remember to create a system restore point before using DevCon

You can use DevCon with Microsoft Windows 2000, Windows XP, and Windows Server 2003 and Vista. You cannot use DevCon with Windows 95, Windows 98, or Windows Millennium Edition.

    Nirmal,

    Very useful tool. I have had problems detecting my usb drive in one of my older machines. Let me see if this is the magic wand I have been looking for. :-)

    Hey, I have a doubt here. There are times when I try to “safely remove hardware” but unfortunately it keeps on giving me a message saying the device is still running. Now, if I ever happen to pull out the USB drive, it just won’t get detected next time unless I restart my machine. Do u think there might be a cure for this phenomenon?

    I have used Devcon. It is a very useful one. But for some license reasons, is there any other tool like devcon? That will help in unattended installation, in command line.thanks.
