The USB cable that came with my Phantom last week has regular USB plug on one end and a mini-USB plug on the other end. The DJI company site's video shows connecting the Phantom to my PC with the supplied USB cable in order to download. However, my PC does not have a mini-USB socket and the Male-to-Female USB extension cord does not seem to connect the Phantom to my PC (the DJI software downloader says it could not find "a device"). Any ideas, please? Must I simply go buy a (different) generic USB extension cord?
