ppk2 - unknown device

Dor Sadeh

Hi, ppk2 is not identified by the power profiler tool. As a side note, Jlink is identified and works ok.

Tried reset, uninstalling and reinstalling power profiler, and uninstalling and reinstalling jlink.

OS: Ubuntu 22.04.2 LTS

nrf connect for desktop 4.0.0

nrfjprog version: 10.19.0 external
JLinkARM.dll version: 7.86

    Hello,

    PPK has two USB connectors. Have you used the right one (USB data/power) when plugging in the USB cable? Is the LED lit/flashing, and which color is it Can you replace the USB cable, connecting it directly to the computer, without using the USB hub? You can also check with another computer to see if it is driver issue or PPK2 hardware/firmware issue?

    Is PPK2 the Unknown device? If the "unknown" is the PPK2, then the USB works but the PPK2 is in some erroneous state or the USB CDC ACM driver / udev rules are not correct, so the USB info is shown incorrectly. 

    Also you can try lsusb and see if the device is listed there.

    Thanks.
