The USB connection is in the middle of the controller under the fold out arms to hold phones, etc. I use it to connect my CS when flying my M2P. Disconnect the cable from the left side of the controller first in order for it to work.As a Mavic 2 Pro owner for 4 days the things I would have wanted is 4K60 and USB-C on the controller. It's really too bad it doesn't have 4K60 but I wanted the portability over the Phantom 4 Pro
Now back to everyone’s great wish lists!
