There are several bug reports for this, ie: https://bugzilla.redhat.com/show_bug.cgi?id=1030802 http://superuser.com/questions/619582/right-elantech-touchpad-button-not-working-in-linux I've spend a couple of hours wading through various bugzillas, launchpads and forum posts to create a list of fw-versions and capabilities for different laptop models to find a good method to differentiate between clickpads and versions with separate hardware buttons. Which shows that a device being a clickpad is reliable indicated by bit 12 being set in the fw_version. I've included the gathered list inside the driver, so that we've this info at hand if we need to revisit this later.
