&lt;p&gt;Could be that the act of&amp;nbsp;&lt;em&gt;plugging in&lt;/em&gt; somehow causes an USB reset for the profiler board. Could also just be a bad USB cable.&lt;/p&gt;
&lt;p&gt;I&amp;#39;d try using a&amp;nbsp;&lt;em&gt;powered&lt;/em&gt; USB hub (i.e. one with its own wall wart power supply) in case the laptop or dock does something&amp;nbsp;&lt;em&gt;funny&lt;/em&gt; when connecting USB devices.&lt;/p&gt;
&lt;p&gt;Alternatively you could try using an USB-C-to-A host adapter on a smart phone/tablet and connect the NRF5240 to&amp;nbsp;&lt;em&gt;that&lt;/em&gt; USB port. This way you don&amp;#39;t mess with the laptop USB at all..&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
