Hard to say one way or the other. If possible you could try another cable. As for you LS4000 that's what I have and it works like a charm. Point being that the fix was tested by me with my 4000.
Also if you're using a IEEE add-in card, you might check to make sure it has proper drivers for Windows 7 as well. Since it's an add-in card, it will need drivers.
Let me know.
