Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device.

 I am trying to program an nRF9160 using a Segger Flasher Compact with J-Link version 7.60e and nrfjprog version 10.15.2 on a machine running 64-bit Windows 10. This was working for a few days but stopped working this morning although nothing changed. I have read through the forum about other people experiencing the same issue and tried all of the fixes suggested. I uninstalled and reinstalled both JLink and the nRF Command Line tools to the latest version. I have tried both the 64-bit and 32-bit versions of these with no success. 

The flasher does appear under device manager: 

Running nrfjprog --com I can see the Flasher:

Can someone please tell me why it is appearing as an unsupported device in nRF Connect for desktop and failing with the command line tools?

Hi Katelyn,

The JLink issues has been fixed in the new release(v3.10.0). Could you also try upgrading to the latest version.? nRF connect v3.7 was also a quick alternate for this.. Perhaps it has something to do with the board itself or the flasher. Are you able to turn ON the board(Does LED5 light up when switching ON the nRF9160DK).? Could you try connecting the device using the normal USB cable provided with the DK and check if the device is detected.?

Kind Regards,

Swathy
