After my first flight I got the drone home. Connected the pc to the drone via USB Cable. Downloaded from sim card to computer. Job done. Today. Connected drone to computer. You can hear a background chime as I plug usb into computer. Then nothing. As though it does not recognise the drive. Things I have tried. Different USB cable. Card out then back in again. Switch drone off then on then plug in. Computer off and back on. re-loaded Downloaded DJI Windows drivers. Re-started computer. Drone on drone off. Restored computer to earlier time. and half a dozen other things Any suggestions? Still awaiting mirco card adapter.
