 I tried SDK v15 sample code - &amp;quot;usbd_ble_uart&amp;quot; on nRF52840-DK. 
 After programming &amp;amp; plug-in USB cable on J3, I can see there are two com port on the device manager. 
 One is J-Link Com Port (ex : COM1) and another is NRF52 USB CDC BLE Demo (ex :COM2</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Wed, 25 Jul 2018 15:52:14 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/36519/nrf52840-sdk-v15---usbd_ble_uart-debug-mode-issue" /><item><title>RE: nRF52840 SDK v15 - usbd_ble_uart debug mode issue</title><link>https://devzone.nordicsemi.com/thread/141392?ContentTypeID=1</link><pubDate>Wed, 25 Jul 2018 15:52:14 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:5163ea60-845a-46bf-89da-e2260dcb061e</guid><dc:creator>Joakim Jakobsen</dc:creator><description>&lt;p&gt;I&amp;#39;m glad to hear that!&lt;/p&gt;

&lt;p&gt;I followed your suggestion to test then it works.&lt;/p&gt;
&lt;p&gt;Thanks.&lt;/p&gt;

&lt;p&gt;What is most likely happening, is that the link breaks as you start the debug session.&lt;/p&gt;
&lt;p&gt;Could you try starting debug mode, and then connect the usb after the debug session is started and see the NRF52 USB CDC BLE Demo will appear?&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;

&lt;p&gt;Maybe you could tell me which nRF52840 IC revision or PDK version you are testing this on?&lt;/p&gt;
&lt;p&gt;&lt;a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52/dita/nrf52/compatibility_matrix/nRF52840_ic_rev_comp_with_dev_hw.html"&gt;IC revisions compability with development HW&lt;/a&gt;&lt;/p&gt;
