Just bought a seacond hand DJI NAZA-M today and got it home to tinker around with the settings. I downloaded all the apropriate programs and drivers and created an account with dji to use the software, Pluged in my DJI NAZA M only to have windows install the wrong driver and have DJI's software not detect the device.
I spent hours surfing the web before I found the solution. DJI does not have signed drivers and windows 10 refuises to install them. So here is how to get your DJI to play nice with Windows 10.
"You may need to refresh this page several times for this article to display properly."
First off you need to enable installation of unsigned drivers.
Hold down the SHIFT key while you click Restart.
Once your computer has rebooted you will be able to choose the Troubleshoot option.
Then head into Advanced options.
Then Startup Settings.
“Disable driver signature enforcement”. To choose the setting, You will need to press the F7 key.
Once your computer Starts back up you have to manually install the driver. Plug your dji device into the computer "supply power from a battery" and open device manager.
You should see your device listed under ports as "USB Serial Device (COM##)".
Now right click that device and click properties and under the Drivers Tab Click Update Driver.
Then Click the "Have Disk..." Button.
Then Browse to this directory
C:\Program Files (x86)\DJI Product\DJI driver2.02\source64
And Select The Dji Driver "dji_vcom_driver11.inf" and hit Open then OK
Hit Next and allow windows to install the driver software anyway.
Your Device Should now look like this in device manager and the DJI software should be able to connect.
Finally enjoy your quadcopter the way it is supposed to work.
