How to find unknown device drivers by vendor and device ID

Reprinted from: http://www.yeeyan.com/articles/view/jht/57657

 

Introduction

Unknown device, no longer headache!

Rule 1: do not lose the drive disc of the device.

Rule 2: exercise caution when saving a backup
.

Rule 3: If your driver file is lost, you need to know where to download it.

Congratulations! If you do not care about the above two items, this article can free you from the three serious crimes you have committed. I am also a sinner. However, the third rule often released me on bail, and I had to pay off my redemption needs thanks to the attachment of the third rule.

Device Manager
Is where all devices are displayed. An unknown device is displayed as a yellow question mark at the corresponding location of the Device Manager. There may be one or more reasons-the device driver system you have installed may not be identified; or the hardware itself may have an error. All of these problems cause devices to be classified as unrecognized devices.

The easiest way to solve these unknown States is to find and download the device driver from the manufacturer's website. On their respective websites, the drop-down menu is usually used to bring you the right driver suitable for your system. But what if you cannot remember the manufacturer or brand of the device? Making mistakes is human nature, and solving it is a sacred duty. Fortunately, correctUnknown Device

Methods exist and are as easy as praying.

 

Use the manual method in the Device Manager

The driver of each device has two authentication codes --Supplier ID
AndDevice ID
. These two numbers can be used to track manufacturers and specific device drivers.Device ID
Is the most unique identifier of a device. The hardware ID can be less specific, and the device ID is the first to be accessed during installation.

1. Open the Device Manager from ......
   • Control Panel-system-hardware-Device Manager (in Windows XP ).
   • Control Panel-system and performance-Administrative Tools-Computer Management-Device Manager (in Windows Vista ).
   • Control Panel
     -Hardware and sound
     -Device Manager (in Windows 7 ).
     [Translator's note]
   • Alternatively, enterDevmgmt. MSC
     .
     
2. Unknown Device
   
   Marked with a yellow question mark.

Select an unknown device and right-click access properties.
In the Properties window, click the Details tab and select a device instance id from the drop-down list.

A letter or digit string, similar
PCI/ven_1217 & dev_7130 & subsys_012f1025 & rev_01
/4 & 6b16d5b & 0 & 33f0 is the identification mark of the device. We only need to extract vendor ID (prefix is VEN) and Device
ID (prefix: Dev ). In this example, the supplier ID is 1217 and the device ID is 7130.

Using the identified numbers, you can use some resources to obtain the suppliers behind these numbers.

PCI Database

It is said that this is the largest PCI device ID central database, which can be used to find your device driver. You can search for suppliers and devices by ID in the search box. Each type of search can give you original device information. Further information can be obtained from the vendor's website or Google search.

How to use the software unknown Devices

A small and free single program is called Unknown Devices
Provides a quick way to get drivers for anonymous devices. This 630 KB software (beta version: 1.4.20) can be run without installation. The database used by the software is three text files in the same directory.

1. This program scans installed devices and displays the manufacturer's name and found devices.

The detailed information includes the supplier and device ID and the name on the manufacturing.

Right-click desired details to search for Google. For example, the hardware ID can be used to find the device driver.
Use the integrated lookup hardware ID Search box to query any hardware ID based on database text.

This beta version (1.4.20) expands its support for Vista.

The information obtained by the above two methods cannot be solved. In some cases, this information will lead us to a dead end because the device driver itself cannot get it. However, these two methods can indeed help us expose unidentified devices and get some details about them. As the device is determined, we can better query the manufacturer or find the right device driver on the Internet.
.

Here we will point out some resources as the beginning of driver search ......

Driverguide.com

With 400,000 drivers, it is basically the king. Free members have some restrictions. For example, a total of more than 100,000 uploaded members can be accessed.
The driver restricts access to more than 300,000 of websites
Upload driver. However, the free access to its large corporate database list and community forums makes it a hub. Because users are allowed to submit drivers, you can request outdated drivers.

About 30,000 drivers are indexed by company name and driver type. Click the link to visit more.

Driversplanet.com

Provides a downloadable driver scanner. This site uses a database containing 120,000 drivers, which are listed by the manufacturer and device type. Let us know how you deal with an unknown deviceDriver

And make it a bit more recognizable.
