I used a virtual machine to flash earlier and now I am trying to connect to host PC directly. As i did not turn off the USB on VM, nordic board is automatically connected to VM and not to host. Issue is resolved when USB on VM is turned off.</p> <p>Please close this ticket&nbsp;</p><div style="clear:both;"></div>
