B12.1.4 Multifunction Devices - Windows Experience


Design Guideline References:
PC 2001 System Design Guide: SYS-0032
Hardware Design Guide 3.0 for Windows 2000 Server, Chapter 3
B12.1.4.1 Separate drivers are required for separate functions with no start order dependencies between separate function drivers

[SYS-0032; SDG3:13]

The operating system must be able to configure and manage functions in any order, so no function on a multifunction device can depend on another function to be started before the function can be started by the operating system.


B12.1.4.2 MFP devices correctly implement driver and Plug and Play support

[SYS-0032]

  • Functional units on a multifunction device do not have start-order dependencies.

  • Resource requirements of one functional unit are not expressed in terms of another functional unit.

  • Operation of one functional unit do not affect or interfere with the operation of another functional unit on the multifunction device or on the system as a whole.

  • Each functional unit is enumerated and its resource requirements communicated to the operating system, so Windows can load the necessary drivers and assign resources to the different units in any order.
B12.1.4.3 Each independent function can be used concurrently, with no hidden dependencies

[SYS-0032]

Separate functional units must be able to operate concurrently, without interfering with each other or with other devices on the system.


B12.1.4.4 Each function can be power managed independently

[SYS-0032]

Each functional unit in a multifunction device must separately meet the power management device class specifications for its device class and be independently power managed. Each functional unit must be able to successfully complete a system sleep/wake transition (where the unit transitions from D0 to D3 to D0) without losing functionality and without requiring user intervention to restore functionality. All functional units on PCI devices that support wakeup capabilities must correctly support wake from D3cold.


B12.1.5 Multifunction Devices - FAQs

B12.1.5.1 Current general FAQs

See http://www.microsoft.com/winlogo/hardware/MF/.
B12.1.5.2 Resource requirements for MFD [Logo Program Clarification]

The PC 99 exception for multifunction PCI devices that use only a single set of relocatable resources refers solely to multifunction devices of the same device class. If different functions within a multiple-function device require separate class drivers—for example, a combination PCI network adapter and modem—then each function must provide a unique PCI SID and SVID that will allow the proper driver to be loaded for each separate function.

Multifunction devices that contain functions from separate classes will not be properly recognized during an operating system upgrade—and therefore drivers will not be properly upgraded—unless unique IDs are provided for each device.

Note that a "supervisory" driver that loads different drivers for the individual functions does not work well with Windows. In particular, driver support is likely to be lost in cases of operating system re-installation or upgrade, or with distribution of new drivers via Windows Update. Therefore, these supervisory drivers should be avoided. The Logo Program requires separate drivers for separate functions.
FAQ Date: May 28, 1999

B12.1.5.3 Exceptions to individual ID requirement for MF devices [Logo Program Clarification]

  • Multiple devices of the same device class, such as a multiline serial device.

  • Dependent video devices, such as a graphics accelerator on a video card.

  • Devices that are generated by an accelerator or auxiliary processor and that do not have independent hardware I/O. That processor must have an ID; under Windows XP/Windows 2000, Mf.sys must be used to enumerate the dependent devices.

B12.1.R Multifunction Devices - Future Requirements


Announcement of additional future requirements will be published at http://www.microsoft.com/winlogo/hardware/MF/.
B12.1.R.1 MFP devices using USB connectivity must appear as part of a composite device

Future requirements for USB connected multifunction print (MFP) device drivers supporting composite implementations are posted at "Multifunction Print Device Design Guidelines" at http://www.microsoft.com/hwdev/mf/mfp.htm.
B12.1.R.2 DELETED
B12.1.R.3 MFP device provides legacy-free interfaces

Future requirement - Legacy interfaces such as parallel (IEEE 1284) or serial are not allowed.
