That's funny, I work with a B&W 350MHz G3 with the AMT8 and I still get the same error. With me it doesn't hurt anything. You get the error and you can ignore it, because all works. But it's not right. I've asked this to Emagic and they told me that something in my connections must be wrong. But they couldn't tell what. I mean, what could go wrong with plugging the appropriate USB-cable in the AMT8 and the other side in the G3? What else can I do? It's the reason why I asked if there would come a new AMT8 driver/extension. Maybe that would help. Remco
