Last month I connected to my pc and checked if everything was ok. Now I want to upgrade and was trying first to connect to my iMac for an upgrade. And the phantom does not get recognice by my iMac. Then I connected to my pc with the same result. I was wondering if I was using the wrong USB cable. I have tried different USB cable with the same result. But I am not sure if I connected with the cable that came with the Phantom. It might be at work with my laptop. So - must I use a spesific usb cable? or can i use every Micro usb cable?
