AMD (which actually make the device) don't have any Mac drivers on their website ether. You could try contacting Diamond or AMD and see if they can find the drivers. But even if they do get back to you with the drivers (which is probably unlikely), it won't work on the recent Mac OS releases. Your best bet will probably be to get a Windows Vista/XP PC (you could try running Windows in a Virtual Machine on your Mac) and use it in that.
