have to do this from a win7 POV i dont know 8 well enough (hate win8)
you should have a tile for desktop click that get to control panel somehow (on the wifes win8 and our test dummy system) i put that icon on the desktop so not sure where to find…
from control panel click system
then device manager, then IEEE 1394 rightclick update software
then browse
then let me pick from list
you will then see the legacy driver
