https://devzone.nordicsemi.com/f/nordic-q-a/27932/segger-embeded-studio-on-linuxHi guys, has anyone had problems with: Cannot connect to J-Link via USB. message? The device is alive and i can flash and connect to it from CLI.

Can you see the JLINK removable folder in the linux file explorer? I guess you can, since you are able to connect via the command line interface. Have you taken a look at <a href="https://devzone.nordicsemi.com/blogs/1032/segger-embedded-studio-a-cross-platform-ide-w-no-c/">this blogpost yet</a>? Also, <a href="https://www.youtube.com/watch?v=YZouRE_Ol8g&amp;list=PLx_tBuQ_KSqGHmzdEL2GWEOeix-S5rgTV">this youtube playlist</a> for getting started with SES might be helpful. It seems to me that this might be some configuration or setting in SES that is incorrect, since you can see the device in Linux. If that doesn&#39;t work, I&#39;ll take a closer look at this issue. Hope that helps a bit!</p><div style="clear:both;"></div>
