Pixhawk and Windows 10 driver issues

I am having trouble connecting Mission Planner to some of my Pixhawk(clones) .
What I have
Windows 7 Laptop
Windows 10 Laptop

1 Pixhawk 2.4.8 (white case)
1 Pixhawk 2.4.8 (black case)
1 RTFHawk (black case)
1 Matek F405-Wing

The Windows 7 laptop can connect to all 4 just fine, all 4 show up in device manager and are functioning.
The issue starts when I try to connect Mission Planner on the Windows 10 laptop. The F403-Wing and the black cased Pixhawk 2.4.8 connect, neither the RTFHawk or the white cased Pixhawk 2.4.8 will connect. In the device manager page it shows as “Legacy FMU” and it is not working.

I am thinking a driver issue, but what drivers to install, and from where??


Hi John,

It sounds like you need to install the Virtual COM port drivers from SiLabs.

CP210x USB to UART Bridge VCP Drivers

Thanks, I’ll give that a shot tonight!

Make sure that you first try using a different USB cord to make sure it is not that. I spent hours reinstalling software and drivers only to find that it was the cheap USB cable that was the issue.
