UDP connection and fireware

Can someone point me in the right direction? I’m trying to get my 3DR Solo up and running on Mission Planner but I can’t get a connection. I’ve tried the USB connection directly into the Pixhawk 2 but my computer can’t see it…does anyone have any pointers or common mistakes I might be making? Can I make the connection via the wifi the Solo already puts out, so I don’t have to tear the Solo down again? I haven’t found any forums on the Solo and it’s Pixhawk 2…anybody?
