AutoStar 497 Firmware Update Steps

[@DanielleGravley]

I am trying to update my autostar with my ETX90 using a very similar cable but am having trouble getting my computer to connect to the controller. When I plug the USB into the computer, it makes the connecting sound so it recognizes there is something in the USB port but no information is coming from the controller. do you have any advice on this matter?

Update. It seems I need a driver for the cable/handset but am unsure where to get that
