This is a newer unit but it was working fine. I updated everything when I first got the phantom just fine. Then a couple of days ago, I enabled the IOC. Everytime I would plug in the usb cable and just get a solid green light. Now when I plug in the cable, it goes to no light at all. I must be doing something silly here but I've rebooted the laptop twice and tried countless try rebooting phantom. Controller seems to talk fine and it flys fine.
