I have got my new Pixhawk unit two weeks ago and spent a few hours on 3 separate computers in the house to try and get it to connect via USB cable. I used multiple cables, powered the Pixhawk direct from the USB port, powered it from an external lab power supply (12.0v, pulling 0.2A), I tried this on two separate Windows 10 PC’s…to no avail. I followed this procedure exactly:
However when I connected the Pixhawk via USB (after I installed the Mission Planner software as well as the USB drivers), I don’t recall the exact error but it would list it as a USB device that was unrecognised. So I tried to manually update the drivers with the PX4 Flow as shown in that tutorial, all I’d get is a USB to Serial A…B…C…D option and nothing that would be PX4 Flow. So I tried every option listed and always got a small exclamation mark in the Device Manager window and it’d never list a COM port.
After struggling with this on two PC’s, one being a laptop that I plan on using MavLink on, I thought to try it on a Windows 7 machine. Plug it in via USB with the same 12v external power supply, once connected the device shows as a COM port…and is shown as PX4 Flow. I can’t believe it. So is there an actual Windows 10 driver that works with the Pixhawk? As I’d like to have a single laptop (Windows 10) that can fully control, monitor and update my automated boat and not have to rely on a Windows 7 machine that is in my garage at home.
