nRF9160 development kit not detected in "Connected Devices" view

Ben_Sc

Hello,

I'm trying to use nRF9160 Development kit and it is not showing up in connected devices view in VS code.

Switch position is correct(nRF91) on the development kit.

It looks like this is J link usb driver issue but I tried with few different versions of J link software 

When installing, I chose install legacy driver option

it says no applications to update as shown below

In the windows device manager, when DK is connected to my laptop, it shows up as USB composite device.

LED5 is solid. LED3 blinks twice, every second. Other LEDs are off.

This is a new development kit and it was never detected so far.

J Link driver status is

How to install legacy USB driver correctly so that this DK is detected properly?

    Hello,

    I tried with "Install legacy USB driver for J-Link" unchecked as well and result is still same. Development kit is not detected.

    J link driver status shown is the output of USB driver status check.

    I tried with Quick start guide as well.

    Following are the screenshot from quick start guide usage and log file

    I tried with programmer and tried to select device and it shows that there are issues with USB drivers.

    Overall, I understand this is due to USB driver issue but not able to resolve, even though I tried to install legacy drivers and multiple versions of segger J link software.

    Hi,

    Can you show the output of "nrfutil device --version"?

    It seems that legacy USB drivers are needed. You can look at prerequisites. You can try to install Segger USB driver for J-Link manually from command line using the command 

    JLink_Windows_V860_x86_64.exe -InstUSBDriver=1

    Best regards,
    Dejan
