WIA Scanner works with TWAIN methods but not WIA methods

I think this is a weird error. I have an EPSON scanner that installs both TWAIN and WIA drivers. If I call TWAINAcquitreToGdPictureImage() with the WIA scanner name it works, but if I call WiaAcquireToGdPictureImage() with the sourceId, it just returns 0. How can this be?
