A driver reports the version of WIA (or STI for legacy drivers) that it supports in the version field that is returned from IStiUSD::GetCapabilities. Drivers typically set this field to STI_VERSION, which is defined in Sti.h.
Windows Vista용 WDK(Windows 드라이버 키트)에서 STI_VERSION 값은 이전 운영 체제의 STI_VERSION 값보다 큽니다. 드라이버 버전에 대한 Windows Vista 값이 있는 경우 Windows Vista IStream 데이터 전송을 지원해야 합니다.
A Windows Vista driver that adheres to the new Windows Vista WIA model must return STI_VERSION_3 in the version field that is returned from IStiUSD::GetCapabilities.
