The driver (we call them backends) is the only part of sane that knows the protocol the scanner speaks. So, the backend would have to be called to perform this task. As an alternative, perhaps the frontend (xsane in this case) could close the scanner when it is idle, and re-open it when the user does something. That would in theory work with all scanners.
