#WINDOWS 7 USB MASS STORAGE DEVICE DRIVER UPGRADE#
I’ve tried compatibility mode on Windows XP and it doesn’t work either, so it’s either upgrade the software or continue using Windows 98. Updating the old software is very expensive, so the decision was to stay with Windows 98 and try to source parts that can support this ageing operating system. The problem is, due to some obsolete software that needs to run on Windows 98, the computer cannot be upgraded to newer versions of Windows such as 8, 7, Vista or even Windows XP. There is actually a third party Service Pack for Windows 98 Second Edition which is still being updated well into 2013, even though Microsoft ended their support for Windows 98 on the 11th of July 2006! Obviously, hardware support from all major manufacturers has ended years ago so if you or your company still run Windows 98 in some capacity, it’s incredibly difficult to find compatible hardware and software for it.Īs an example, a company I did some work for a while back purchased a Kingston Data Traveler USB flash drive for backup purposes on a computer that’s still running Windows 98.

For more information, see "USB Video Class Driver" under AVStream Minidrivers.Although Windows 98 has been out of general circulation for well over a decade now, it might come as a surprise to some people that it’s still actively in use, especially in a business or specialized environment for running old software. Microsoft provides USB video class support by means of the Usbvideo.sys driver. Windows 11Windows 10 for desktop editions 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.
