All- I appreciate your patience with some basic questions I've posted here. I really only post on things that, obvious or not, really stump me. I am attempting to install the DJI Driver Installer and a dialog box pops up asking "Is the main controller is powered up and attached to the PC via USB cable?" I know how to attach the PV2 to the computer, but I can not find any USB connection on the controller (except for the mini USB on the WIFI Range Extender). How do I attach the controller to the computer?? Thanks in advance!
