Hi Bob, just to verify, have the Assistant and driver been installed properly? You may check whether the cable is connected well and change the USB cable or port to see whether it helps.
Alternatively, you may disable the anti-virus software firewall, or change another PC and reinstall the Assistant to confirm: https://www.dji.com/naza-m-v2/faq

the v2 still shows up as a dji serial port but the assistant software won't accept it as a device

sorry should have said this in last post tried new cable computer and turning off all other tasks running

Thanks for getting back to us. May I know what's the OS of your PC? If it is the Windows 7, you may refer to the below FAQ and check: https://www.dji.com/naza-m-v2/faq If still no luck, I'm afraid that you may consider sending the unit in for diagnosis, sorry about this.

Hi Bob, it is recommended to connect to a Windows 7 system computer to try again, if the issue persists, the device will need to be sent in for further evaluation. Sorry for the inconvenience caused.

Ok I tried all that how do I send it in for Diagnostics and what does that cost?

thanks
