B18.104.22.168 ATA Flash Cards [Logo Program clarification]
A PC Card ATA flash card must support at least one LogConfig with an IRQ resource. Under Windows Me, Configuration Manager (which is responsible for assigning resources) filters the LogConfigs of ATA cards. If an IRQ is not available, then that configuration is ignored. The operating system will not assign resources for a device that has no LogConfig with an IRQ. This requirement is effective July 1, 2000.

B22.214.171.124 Windows Me: USB Mass Storage and Cameras [Clarification]
It is possible to create a camera that appears to the operating system to be a storage device (and not a camera) by supporting the USB Mass Storage Class specification in camera firmware. In this case, the device is a storage device and must adhere to storage specifications.
However, Microsoft will not grant a "Designed for Windows" logo to cameras that only appear as hard drives to Windows. The reason for this exclusion is that such a device is specifically not designed for Windows, and it loses functionality when attached to a Windows-based PC.
A camera that is designed for Windows retains camera functionality when attached, so the user can take advantage of the imaging feature sets in Windows Me and Windows XP.

B126.96.36.199 Windows Me/Windows XP—Requirement for Still Image Devices [Clarification]
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:
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 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 Me and Windows XP provide 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. In Windows 2000 and Windows 98, event-driven STI user-mode minidrivers remove unnecessary steps for device interaction with the operating system. In Windows XP and Windows Me, 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.
