I have a Cognisys focus rail with their controller box. There is a cable from the controller box to the focus rail, a USB cable from the controller box to my laptop, and a USB cable from my Canon camera to my laptop. The controller box is plugged into the wall.
I used this setup for years. When I click on <<<, <<, <, >, >>, or >>> in Helicon Remote the focus rail moved appropriately. Now it doesn't. If a click on any of those buttons in Helicon Remote the green progress bar shows a moving bar as if the focus rail was moving, but the focus rail doesn't move.
In short, this is something I've done hundreds of times before in exactly the same way but suddenly it has stopped working. Any ideas?

Re: focus rail doesn't focus
I fixed this myself. I unplugged the controller box, then unplugged and replugged every cable into it. Now it works. So there was a loose cable connection.
