I love my vision, but I am having no luck in updating the firmware. I tried to search this board for help, but I get this error message: The following words in your search query were ignored because they are too common words: upgrade firmware vision. You must specify at least one word to search for. Each word must consist of at least 3 characters and must not contain more than 14 characters excluding wildcards. When I launch the Vision Assistant, it looks like a red status bar that is 2/3 finished, but doesn't move. I have to click SKIP. Then when I press the Phantom 2 Vision button at the top, I get a message "Please connect to the controller." Same message on 2 computers, a Windows 7 and an 8. So am I supposed to be connecting the Vision controller to the computer via USB? Do you open the back? What is the USB on the Vision itself for?
