Announcement of additional future requirements will be published at http://www.microsoft.com/winlogo/hardware/.
B9.0 Still Image Devices
All general requirements in B1.0 are included by reference.
All bus-specific requirements in B2.0 are included by reference.
B9.1.1 Still Image Devices - Windows Compatibility
Digital still cameras that stream video while tethered must have WDM stream class drivers as defined in "Still Image Devices" in the Windows DDK.
B9.1.1.1.1 Vendor provides a WIA driver or supports Picture Transfer Protocol (PIMA 15740) in camera firmware. -
Scanner vendors must provide a WIA driver. Digital camera vendors can implement one of the following solutions:
-
Provide a camera-specific WIA driver.
-
Ensure the camera firmware adheres to the mandatory commands in the PTP (PIMA 15740) standard.
-
Implement support compliant with the USB Mass Storage Class Bulk-Only or CBI specification and use the Microsoft Usbstor.sys storage driver.
Still image devices are supported under WIA architecture or PIMA 15740. For the Windows Logo Program, the scanner vendor must provide a WIA driver. For digital cameras, however, vendors have theses options:
-
Provide a camera-specific WIA driver.
-
Ensure the camera firmware adheres to the mandatory commands in the PIMA 15740 standard.
-
Implement support compliant with the USB Mass Storage Class Bulk-Only specification and use the Microsoft Usbstor.sys storage driver.
These choices are available because Windows provides a WIA driver for PIMA 15740 and USB Mass Storage Class devices, accomplishing the same functional purpose.
Note: Optimal user experience is seamless integration of the imaging peripheral with the Windows environment. The operating system detects hot-pluggable WIA devices such as digital cameras, providing a seamless interface with the device. For persistent-connection devices, such as scanners, implementation of device events via buttons and sensors will deliver this functionality after initial installation.
See "Still Image Drivers" in the Windows DDK.
B9.1.1.1.2 DELETED B9.1.1.1.3 Driver supports TWAIN 1.7, if TWAIN support is implemented.
For devices with a TWAIN data source, the device driver must support the TWAIN Specification, Version 1.7, ensuring that the device can run without a hardware-specific user interface and download n number of images at a single time.
