3 Ways To Find Unknown Device Drivers In Windows

Device driver installation has always been a headache for most of the people. Either one thing or the other is always missing. Once we want to clean install Windows, we have to make sure that we have got all the device drivers for our system. If we miss some of the drivers, nothing works fine. Here are some ways to find unknown device drivers in Windows.

1- Using Unknown Device Identifier

Unknown Device Identifier enables you to identify the yellow question mark labeled Unknown Devices in Device Manager. And reports you a detailed summary for the manufacturer name, OEM name, device type, device model and even the exact name of the unknown devices. With the collected information, you might contact your hardware manufacturer for support or search the Internet for the corresponding driver with a simple click. With this utility, you might immediately convert your unidentified unknown devices into identified known devices and find proper driver on the Internet and contact the hardware device manufacturer or vender. Known devices recognized by Microsoft Windows will also be analyzed independent of the operating system.

2- Using Unknown Devices

Unknown Devices helps you find what those unknown devices in Device Manager really are.
By checking Device Manager for unknown devices and extracting information from it, this program attempts to figure out what the device is. You might not have to open your case or look up random numbers off of PCI cards to figure out what they are.
However when I run this software on my Windows Vista machine, it doesn’t detect my operating system. I have updated the vendors database file and packed with this software. The software can be downloaded from the following location:

3- Manually Identifying The Unknown Devices

To manually identify the devices we have to find out the device instance ID which has two parts, one is the vendor ID and the second is Device ID. Once we have got the vendor ID and identified the device ID, we can easily find the drivers for our device.
To find the device instance ID go to Device Manager –> Right click the unknown device –> Properties –> Details.
Now from the drop down menu select Device Instance Path (Windows Vista)/ Device Instance ID (Windows XP)
It will give you a string value which contains the vendor ID and the Device ID. The string is like this:
Where red is the Vendor ID and green is the Device ID. Note down both of them.
device instance path
Once you have the Vendor ID and the device ID, you can go to the following websites and find out the vendor and device name and search for its drivers.
You can also download PCI Utilities which displays the Vendors and devices in human readable format instead of the alphanumeric code characters.

    Don’t be so blatantly ignorant. Not everyone uses Win 7… In fact barely anyone compared to the amount of people using xp and vista. Go dig a hole and die in it.
    Oh, and the article is helpful. 🙂

  7. Henrik

    No need for me to dig hole as your mother already having a hole, i am ready to die in it, pls send ur mother.

    Unknown Device Identifier is a trojan.

  12. Henrik’s Mom

    Tisk tisk Sanix, you should do your homework before promoting virus transfers.

  13. Sanix

    @Henrik’s Mom what do you mean? Can you explain your point in detail please? If it’s a trojan, I’ll remove it. I do not have any intention of putting malware on my site.

  14. Scotty

    No trojan it’s ok Sanix. I think Henrik’s Mom just needs to get laid

    I just found Unknown Device Identifier version 7.00 was just released yesterday. It’s my favorate utility to identify unknown devices. http://www.zhangduo.com/udi.html

    It does’t work on win7. In win7 you have only Device Instance Path which contains (in my case) somethink like ACPI\ATK0110\1010110. So no vendor and no device numbers 🙁

    Thank you so much! more power..

  23. Alexandre

    Thank you so much! This is the first time in years I have all my devices recognized.
    I´d recommend the third method (manually identifying). It solved all my problems.

  24. yellahfellah

    Thank you very much for this very useful info!!! I used the software to identify a device for which the supplied drivers did not work. From there, I went to the manufacturer’s website and downloaded the appropriate driver. The device now works. Thanks!!!
