New nRF52840 Preview DK is not recognized by Windows 10 when connecting through USB.

First time turning the board on by connecting to a PC running Windows 10 through USB. The power button starts blinking which is odd, I expected it to be solid green. There is no JLINK drive  in Windows. The default demo firmware seems to be running fine since LED 1 flashes and I can switch between LEDs 1 ... 4. Is the board defective? I tried a PC running Windows 7 with same results.

Hi,

Have you tried with a different USB cable? This symptoms are similar with what you get with a charge-only USB cable (no data lines, only power).

Best regards.

Hi,

You are right. I changed the cable and it works fine now. Thanks for your help.
