I'm using a Lacie USB Driver to enable my USB 3.0 Card to work, but when the driver is installed my USB Soundsticks aren't seen anymore. Situ is same in Snow Leopard and Mountain Lion. It's not the presence of the card causing it, I believe, because when card is installed w/o a driver the Soundsticks are seen by the system just fine. Makes me think it's something about the Lacie Drive. Puzzling. R.W.
