1- Using Unknown Device IdentifierUnknown 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:
Unknown Devices (462.2 KiB, 9,603 hits)
3- Manually Identifying The Unknown DevicesTo 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.
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.
