Using a Braille edge with NVDA

Hess, John (DEED) <john.hess@...>

Good day to all. I have set up the Braille edge 40 with the latest release of NVDA on a windows 7 machine and I can read the output of the machine however none of the controls on the display do anything. I am not able to move through menus or text. I am using the latest hims driver. Is this the way it’s supposed to work and if not, what am I missing?
