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.
Windows categorizes devices by device setup classes , which indicate the functionality of the device. Microsoft defines setup classes for most devices. This class is not used for USB host controllers and 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.
In Device Manager, the device is shown under is Sound, video and game controllers , which indicates that the device setup class is Media. For more information, see USB serial driver Usbser.
See, MB Interface Model. For a description of the role that Usbscan.

You should probably use the driver included in Unless its very old, there should be one. Failing that, try the XP one. In general XP and drivers are interchangable, but I'm sure there are exceptions.
