USB Attached SCSI (UAS) Best Practices for Windows 8.Loading a UASP Storage Driver as a Class Driver on xHCI.Uaspstor.sys is the class driver for SuperSpeed USB devices that support bulk stream endpoints. Windows 10 for desktop editionsWindows 10 MobileWindows 8.1Windows 8 For information about Windows storage support, see the Storage Technologies website. For an example device stack that is managed by this driver, see Device Object Example for a USB Mass Storage Device. Microsoft provides the Usbstor.sys port driver to manage USB mass storage devices with Microsoft's native storage class drivers. Windows 10 for desktop editionsWindows 10 MobileWindows 8.1Windows 8Windows 7Windows Server 2008Windows Vista For information about implementation of the printer class in Windows, see the Printing - Architecture and Driver Support website. Microsoft provides the Usbprint.sys class driver that manages USB printers. Note Usbprint.sys enumerates printer devices under the device set up class: Printer For a description of the role that Usbscan.sys plays in the WIA, see WIA Core Components. For more information about WIA, see Windows Image Acquisition Drivers and the Windows Imaging Component website. This driver implements the USB component of the Windows Imaging Architecture (WIA).
Microsoft provides the Usbscan.sys driver that manages USB digital cameras and scanners for Windows XP and later operating systems. Windows 10 for desktop editionsWindows 8.1Windows 8Windows 7Windows Server 2008Windows Vista Two important device setup classes for USB devices are as follows: For more information, see System-Defined Device Setup Classes. IHVs and OEMs can define new device setup classes, but only if none of the existing classes apply. Microsoft defines setup classes for most devices. Windows categorizes devices by device setup classes, which indicate the functionality of the device.

The current list of USB class specifications and class codes is documented in the USB-IF Defined Class Code List. 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.įor general information about USB-IF approved device classes see the USB Common Class Specification Windows class drivers might not support all of the features that are described in a class specification. Hardware vendors should not write drivers for the supported device classes. 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. Microsoft provides in-box drivers for several of those device classes, called USB device class drivers. 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. Those classes and their specifications are defined by the USB-IF. USB Device classes are categories of devices with similar characteristics and that perform common functions. More guidelines are included in Choosing a driver model for developing a USB client driver. 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. 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. The drivers are updated through Windows Update.
They are available in the \Windows\System32\DriverStore\FileRepository folder. These drivers and their installation files are included in Windows.

If you are installing USB drivers: You do not need to download USB device class drivers. For non-composite devices or a function of a composite device, use WinUSB (Winusb.sys).For composite devices, use USB Generic Parent Driver (Usbccgp.sys) that creates physical device objects (PDOs) for each function.Microsoft-provided drivers for USB-IF approved device classes.This topic lists the Microsoft-provided drivers for the supported USB device classes.
