Odm Manufacturer Multifunction Devices Driver


A multifunction device occupies one location on its parent bus but contains more than one function. Combination printer/scanner/fax devices and modem/network cards are common multifunction devices.

In a multifunction device, the individual functions are independent. This means the functions must have the following characteristics:

Gigatek Inc., Taichung Taiwan — Full-service Original Equipment Manufacturing (OEM), Original Design Manufacturing (ODM) and Electronic Manufacturing Services (EMS) provider. Top Union Electronics Corp. — Established in 1990 and currently operates one plant in Taiwan and two plants in China, encompassing more than 950 employees. This package contains and installs the appropriate drivers for printing and scanning to your Xerox device, including: Easy Document Creator-1.05.99 Easy Print Manager- Easy Wireless Setup - 3.70.18 TWAIN-2.1.27 OCR 1.01.21 Win PS Print Driver- Win PCL Print Driver-3.13.59 Fax Driver-1.10.24. This driver supports IP address search for non-broadcasting printers.It also supports local scanning through USB on some devices.; Network and Local scan driver for 64-bit Linux distributions with RPM-based packaging.

  • The functions cannot have start-order dependencies.

  • The resource requirements for one function cannot be expressed in terms of the resources of another function (for example, function1 uses I/O port x and function2 uses port x + 200).

  • Each function must be able to operate as a separate device, even if it is serviced by the same drivers as another function.

  • Each function on the device must be enumerated.

  • Resource requirements for each function must be communicated to the PnP manager.

  • There must be INF files and drivers for each function.

The component responsible for each of these tasks depends on the multifunction standard for the device's parent bus, the extent to which the device conforms to the standard, and the capabilities of the parent bus driver.

If the device complies with the multifunction standards for its bus, your driver requirements are significantly reduced. Industry-wide multifunction standards have been defined for the PC Card and PCI buses.

If you are working with a multifunction DVD/CD-ROM device used for data storage (not for audio/video playback), you should use the system-supplied WDM DVD class driver, which treats the device as a single logical unit.

For a multifunction device that combines other functionality, you can use a system-supplied driver and INF file if the device complies with the multifunction standards for its bus. The system supplied multifunction driver (mf.sys) can handle the bus-level enumeration and resource allocation requirements for the device, and the system-supplied INF (mf.sys) can install the multifunction device. You need to supply only a function driver and INF file for each of the individual device functions.

If the device does not comply with the standard for its bus, you might need to supply a driver equivalent to mf.sys in functionality, in addition to function drivers and INF files for the device functions.

To install a multifunction device, you typically provide a base INF file for the device and an additional INF file for each of the device's functions. The base INF file typically copies the INF files for the device's individual functions. For information about how to accomplish this, see Copying INFs.

The following sections describe driver and installation requirements for various types of multifunction devices:

See INF File Sections and INF File Directives for information about INF file syntax.

The Windows Driver Kit (WDK) includes a separate section that describes how to support multifunction audio devices.

Device Stage is a new Windows platform that enables device manufacturers to deliver rich user experiences that match the specific branding, features, and content of their devices. With Device Stage, users can simply connect their device to a Windows 7 PC, and the manufacturer-supplied experience will be automatically installed and presented to the user, ensuring a seamless experience between the device and PC.

Device Stage is closely linked to the other prominent Windows Device Experience end-user feature, the Devices and Printers folder. A Device Stage experience contains all the elements necessary to work with both the Device Stage platform and the Devices and Printers folder. Users navigate to Device Stage by first navigating from the Windows Start menu to the Devices and Printers folder, where they will find the photo-realistic icon that represents their physical device. Double-clicking on the icon opens Device Stage. For nomad devices, Device Stage shows the device directly on the Windows taskbar when the device is currently connected.

A Device Stage experience is made up of XML and graphics files. These files define the functionality and branding to be used by the Device Stage platform when rendering the experience. These files also contain device-specific information, including identifying information about the devices for which the Device Stage experience should be presented. The files are assembled together into a device metadata package for easy distribution. A validation system run by Microsoft digitally signs the package and its components after determining that the associated devices meet certain quality requirements, such as those set by the Windows Hardware Certification Kit (HCK). The Device Stage experience must also be well-formed and meet the requirements for the device class. Microsoft hosts a Web service for global distribution of device metadata packages to Windows PCs. Device metadata packages are automatically retrieved and processed by Windows when a device is connected to the Windows PC.

Device Stage provides several advantages to device makers:

  • Increased customer connection

    Device Stage provides a highly customizable user interface that places your device in the center of the Windows experience. Custom logos, rich graphics, and device images reflect your unique product and corporate branding on the desktop.

  • Richer desktop experiences

    Windows 7 provides a rich set of device functionality such as setting print preferences, scan a document, view contents of storage, and many more. With Device Stage you can include key device functionality in your device experience without having to develop, download, and install additional software.

  • Deploy and update device experiences anytime

    Windows 7 Device Stage automatically retrieves the latest device experience metadata for the device from WMIS service. You can update the data on the service at anytime, ensuring that you retain complete control over the experience and that users are given the most current applications, services, and content for their device.
