Control de versiones del controlador WIA

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.

En el Kit de controladores de Windows (WDK) para Windows Vista, el valor de STI_VERSION es mayor que el valor de STI_VERSION en sistemas operativos anteriores. Si un controlador tiene el valor de Windows Vista para su versión del controlador, debe admitir transferencias de datos de IStream de Windows Vista.

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.
