I have seen the same issue reported.
nRF52840 DK does not appear as a removable drive named "JLINK"
Done the following.
1- My laptop has only one USB port. So I have used a USB docking docking station to expand the USB.
2. Used a micro USB 2.0 Data cable(Fully functional and tested) to connect the nRF52840 DK to one of the docking staion's USB port.
3-LED 1 has started pulsating 9nRF power source switch SW9 in Vdd). SW* is ON position
4- Toggling buttons SW1 to SW4 caused LED1 to 4 to light up. LED1 pulsates slowly.
5- No removable drive named "JLINK" appeared on my computer(windows 10)
Any suggestions ?
thanks
