Start with downloading libfprint sources from git, see development section of http://www.freedesktop.org/wiki/Software/fprint/libfprint/ Driver you're interested in is at libfprint/drivers/vfs301.c A driver has to start another capture after successful (or unsuccessful) previous one, unless imgdev core didn't explicitly ask to stop scan by calling dev_deactivate(). But currently vfs301 driver doesn't support deactivation properly (see dev_deactivate() function, it doesn't even bother to cancel flying transfers). You need to modify the driver to respect this requirement and fix dev_deactivate() to do proper deactivation.
