USB Video Class driver overview

If you are providing a driver for a webcam or a digital camcorder, consider using the system-supplied universal serial bus (USB) Video Class driver, Usbvideo.sys. The USB Video Class (UVC) driver is a Microsoft-provided AVStream minidriver that provides driver support for USB Video Class devices. When your device uses UVC, you do not need to supply your own driver. Instead, the device works automatically with the system-supplied driver.

In the USB Video Class model, vendors do not write drivers; instead, vendors implement video streaming hardware according to the guidelines in the Universal Serial Bus Device Class Definition for Video Devices Specification document located on the USB Implementers Forum website. The UVC driver queries the hardware directly to obtain its capabilities and then drives the device, with no proprietary driver required.

You can optionally extend UVC driver functionality to add vendor-specific processing.

The following table shows support for UVC in different versions of Windows:

Beginning with WindowsВ 8, the H.264 video codec (encoder/decoder) is supported. H.264 is an open standard that allows efficient video compression techniques for reducing the use of network bandwidth and storage space. This leads to a higher video quality for a given bit rate. For more information, see USB H.264 Video Cameras Support. Also refer to Microsoft Proposed Extensions to the USB Video Class for H.264.

The following list shows some advantages to using the Usbvideo.sys driver:

No CD required for installation

No driver writing cost

No maintenance cost

Opportunity for vendors to add functionality

Easier debugging with public symbols

Works with Driver Verifier

Works with checked OS builds

Compliant with ACPI power management

Compliant with Selective Suspend power management

Supports multimedia APIs in Media Foundation and DirectShow

The system-supplied Usbvideo.sys driver supports the following UVC features in different versions of Windows:

Customizing the UVC Driver

You can customize your support for UVC by supplying an Extension Unit plug-in. Extension units provide a private control channel between device and vendor-supplied application.

Additional Resources

To test your UVC implementation, you can use the following tools:

For more information about these tools, see AVStream Testing and Debugging.

You can find specifications for USB Video Class 1.1 on the USB Implementers Forum website.

Windows 10 не распознает USB, что делать?

Проблемы с USB относительно распространены, и многие пользователи сообщили, что Windows 10 не распознает USB. Говоря о проблемах USB, пользователи также сообщили о следующих проблемах:

Ранее мы много писали о проблемах с USB. Добавьте эту страницу в закладки, если она понадобится вам позже.

Исправлено – Windows 10 не распознает жесткий диск USB/USB-накопитель

Иногда, из-за функции быстрого запуска, ваш жесткий диск USB может не распознаваться Windows 10. Это может создать всевозможные проблемы, особенно если вы используете USB-накопитель для хранения важных данных.

К счастью, вы можете легко исправить это, выполнив следующие действия:

После отключения быстрого запуска Windows 10 может начать работать немного медленнее, но все жесткие диски USB должны быть правильно распознаны.

Решение 2. Обновите драйверы/установите драйвер по умолчанию

Если это не сработает, вы можете удалить установленный драйвер и позволить Windows 10 установить драйвер по умолчанию. Для этого выполните следующие действия:

Узнайте все, что нужно знать об обновлении драйверов в Windows 10, с помощью нашего полного руководства!

Обновлять драйверы автоматически

Этот инструмент предназначен для Windows 10, одобрен Microsoft и Norton Antivirus для обновления вашего ПК с правильными драйверами Windows. Вот краткое руководство о том, как это сделать.

Примечание. Некоторые драйверы необходимо устанавливать в несколько этапов, поэтому вам придется нажимать кнопку «Обновить» несколько раз, пока не будут установлены все его компоненты.

USB device class drivers included in Windows

This topic is for programmers. If you are a customer experiencing USB problems, see Troubleshoot common USB problems

This topic lists the Microsoft-provided drivers for the supported USB device classes.

If you are installing USB drivers: You do not need to download USB device class drivers. They are installed automatically. These drivers and their installation files are included in Windows. They are available in the WindowsSystem32DriverStoreFileRepository folder. The drivers are updated through Windows Update.

If you are writing a custom driver: Before writing a driver for your USB device, determine whether a Microsoft-provided driver meets the device requirements. If a Microsoft-provided driver is not available for the USB device class to which your device belongs, then consider using generic drivers, Winusb.sys or Usbccgp.sys. Write a driver only when necessary. More guidelines are included in Choosing a driver model for developing a USB client driver.

USB Device classes

USB Device classes are categories of devices with similar characteristics and that perform common functions. Those classes and their specifications are defined by the USB-IF. Each device class is identified by USB-IF approved class, subclass, and protocol codes, all of which are provided by the IHV in device descriptors in the firmware. Microsoft provides in-box drivers for several of those device classes, called USB device class drivers. If a device that belongs to a supported device class is connected to a system, Windows automatically loads the class driver, and the device functions with no additional driver required.

Hardware vendors should not write drivers for the supported device classes. Windows class drivers might not support all of the features that are described in a class specification. If some of the device’s capabilities are not implemented by the class driver, vendors should provide supplementary drivers that work in conjunction with the class driver to support the entire range of functionality provided by the device.

For general information about USB-IF approved device classes see the USB Common Class Specification

The current list of USB class specifications and class codes is documented in the USB-IF Defined Class Code List.

Device setup classes

Windows categorizes devices by device setup classes, which indicate the functionality of the device.

Microsoft defines setup classes for most devices. IHVs and OEMs can define new device setup classes, but only if none of the existing classes apply. For more information, see System-Defined Device Setup Classes.

Two important device setup classes for USB devices are as follows:

USBDevice <88bae032-5a81-49f0-bc3d-a4ff138216d6>: IHVs must use this class for custom devices that do not belong to another class. This class is not used for USB host controllers and hubs.

USB <36fc9e60-c465-11cf-8056-444553540000>: IHVs must not use this class for their custom devices. This is reserved for USB host controllers and USB hubs.

The device setup classes are different from USB device classes discussed earlier. For example, an audio device has a USB device class code of 01h in its descriptor. When connected to a system, Windows loads the Microsoft-provided class driver, Usbaudio.sys. In Device Manager, the device is shown under is Sound, video and game controllers, which indicates that the device setup class is Media.

Solution 1: Try a different USB port

First and foremost, you should make sure there is no problem with the USB port. You can disconnect the USB device which cannot be recognized by Windows and then reconnect it via a different USB port. Do not connect the USB device via USB hubs. In many cases, the «the last USB device you connected to this computer malfunction» error is just temporary, and changing a USB port should get rid of the error.

If your computer is a desktop, then you can also try connecting the USB device to computer via the USB port on the back of the case. Those USB ports placed at the back of computer case usually have better power supply.

Besides, you can try the USB device on a different computer and check if the error still appears.

Solution 2: Rescan the device in Device Manager

There are some cases that the USB device not recognized is caused by operating system conflicts, which can be solved by rescanning the device in Device Manager.

Step 1. Log into Windows 10 or Windows 11 with your administrative account and open Run dialogue via pressing Windows and R keys.

Step 2. Type «devmgmt.msc» in Run box and press Enter key, which opens Device Manager. You can also launch Device Manager by right-clicking the Start button > choosing «Device Manager».

Step 3. In Device Manager, click «Action» menu and select «Scan for hardware changes» option. Then system will try to connect to any new devices connected to your PC. If your USB device still cannot be recognized after scanning, you should go on trying other solutions.

Solution 3: Remove computer power supply

This is a super easy solution! If this solution works, you’ll save a lot of time. Unplugging computer power supply does not mean simply turning off computer with the power button. That’s because most computers do not actually shut down completely, as the motherboard still gets power. Thus, you need to remove power battery from laptop or unplug power supply from the back of computer case.

Motherboard is the very place where all hardware is connected, including USB ports. Sometimes the motherboard should be rebooted when things go wrong. When power is removed, the microprocessor on the motherboard will reload drivers for USB ports, after which the USB device might be recognized again. Therefore, you can try shutting down computer and removing power supply for a while, and then plugging it back and restarting Windows.

Besides, the USB not recognized issue in Windows can also be caused by a dirty or loose RAM. Thus, after removing power supply you can manually remove the RAW and clean it. Cleaning RAM can also help a bit in improving speed.

Solution 4: Update USB device drivers

USB devices are connected to computers via USB ports, via which they become able to communicate with host controllers on motherboard. And the process is managed by driver software. Drivers are responsible for being an instruction which can be read by computer to interact with devices. Drivers contain various manuals which tell computer where it attempts to perform basic input/output actions with connected devices. When you get USB not recognized error, it is likely that there is something wrong with device drivers. Hence, this problem can be removed via fixing incorrect or outdated drivers. Here is how to update USB device drivers.

Step 1. Open Device Manager. Right-click on Start menu and select Device Manager option from Start menu; if you are using Windows 7, you need to right-click on Computer icon and select «Manage», after which you can select «Device Manager».

Step 2. Browse and expand Universal Serial Bus Controllers, and you can find the device is tagged as Unknown devices.

Step 3. Right-click on the Unknown Device and select Properties. Then select Driver tab from the Properties window.

If this does not work, you can try updating drivers manually: go to the website of the device’s manufacturer and download the latest drivers. Then run the driver installer to get drivers installed, after which you need to restart computer.

Solution 5: Fix USB root hub

There are some cases that USB device does not work properly issue is caused by improper power management settings. So you can try following steps to fix it.

Step 1. Still open «Device Manager» and expand Universal Serial Bus Controllers to locate items like USB Root Hub.

If there are multiple USB Root Hubs on your computer, you need to repeat this operation on all of them.

Solution 6: Uninstall hidden devices

By default, Windows Device Manager does not show all devices installed to computer, as it displays those that you are operating. Sometimes some hidden devices may conflict with connected devices and cause the problem. So we can view all hidden devices and uninstall useless devices to avoid any issues.

Step 1. Launch Command Prompt as administrator. For Windows 10 users, you can type cmd in searching box, and you will see «Command Prompt» app in searching result. Click Run as administrator.

Step 2. Type following commands in Command Prompt and press Enter after each command:

set DEVMGR_SHOW_DETAILS=1

set DEVMGR_SHOW_NONPRESENT_DEVICES=1

start devmgmt.msc

Step 3. Now Device Manager is launched and you should click View menu and choose «Show hidden devices» option.

Step 4. You can identify devices which are greyed out and unknown device. Right-click one and choose Uninstall. Repeat this action until all problematic devices are removed.

Solution 7: Disable USB selective suspend settings

The USB selective suspend setting is a feature provided to assign certain USB port to a power saving mode, which works like the computer’s sleep mode. Such feature is very useful when your laptop or tablet is only on battery. However, if you are using a desktop, this feature is not necessary, and sometimes causes USB device not recognized issue. Here is how to disable it:

Step 1. Type «power plan» in searching box next to the Start menu. Then click Choose a power plan from searching result.

Step 2. Select Change Plan Settings next to your currently selected plan. Then choose Change advanced power settings.

Step 3. On the «Power Options» window, you can select the power plan that you want to customize, and then choose settings that reflect how you want your computer to manage power. Then browse items in the box to expand «USB settings» and then expand» USB selective suspend settings«.

Step 4. Choose «Disabled» from the drop-down list. Then click Apply and OK button to save changes.
