You can not decide how other program would call your driver. Most of programs will use DirectShow. Some would use the win3.x technology VFW. Many new programs, including Windows XP's scanner and camera wizard, may call you via the WIA interface. If you do not want to implement all that, you need to at least provide the DirectShow interface via WDM and let vfwwdm32.dll gives you a VFW interface, or write your own VFW driver.
