you wouldnt need a cable. After you download the file
Unzip the file and load it onto a USB thumby drive
plug thumby drive into receiver
in the menus there is an option to download software from drive
I've never used one of these drives before, so I'm unfamiliar with them. So I did some searching..will the following then work?
