Find Hardware IDs via Device Properties
Use the built-in Details tab in Device Manager to extract the unique Hardware ID of the unknown device, allowing you to search for the exact official driver.
Every piece of hardware connected to your computer has a unique identifier containing a Vendor code (VEN/VID) and a Device code. By retrieving these codes, you can accurately identify the component and locate the official driver on the manufacturer's website.
Right-click the Windows Start button and select 'Device Manager' from the context menu, or search for it directly in the taskbar.
Locate the 'Other devices' section, right-click the unknown device with a warning icon, and select 'Properties'.
Click on the 'Details' tab. Under the 'Property' drop-down menu, select 'Hardware Ids'.
Look for the text values beginning with PCI\VEN or USB\VID. Right-click the top value and select 'Copy'.
Search for the copied Hardware ID on a web search engine to identify the device name. Then, navigate exclusively to your computer manufacturer's or the specific component manufacturer's official support page to download the relevant driver.

Frequently Asked Questions
What does PCI\VEN or USB\VID mean in the Hardware Ids list?
PCI\VEN stands for Peripheral Component Interconnect Vendor, and USB\VID stands for USB Vendor ID. These are standardized alphanumeric codes assigned to hardware manufacturers, helping Windows and users uniquely identify the maker of a specific component.
Why do some devices show up under 'Other devices' with warning icons?
This happens when Windows detects that a piece of hardware is physically connected to the computer but cannot find the appropriate built-in driver software required to communicate with and operate it.
Are third-party driver download websites safe to use?
It is highly recommended to avoid third-party driver download sites and third-party driver update tools. They can often provide incorrect, outdated drivers or bundle malicious software. Always download directly from the official hardware manufacturer.
How can I check my computer model before searching for drivers?
Press the Windows key + R, type 'msinfo32', and press Enter. This will open the System Information window, where you can find your exact 'System Model' and manufacturer details.
