Hello,

The serial number is correct that is listed in software. So, PPK can recognize this correctly in OS level. There is something wrong with software. I will talk to respective team about this and will let you inform lately.

Can you try to do lsusb -v to get more vervose output something like this?

If you can find the ppk listed by doing following command, then we can say USB is working, issue lies elsewhere.

lsusb -v |grep "PPK2" -a10 -b10

The usb cable is connected to the Data/Power port. Regarding leds on ppk2 - green led, blinking slowly.

ppk2 is the unknown device for sure, e30abdaa is the serial number on ppk2.

typing lsusb detects the ppk:
Bus 001 Device 012: ID 1915:c00a Nordic Semiconductor ASA PPK2

In a few days time I could have access to other ppk2 and test it on my computer, and also try this ppk2 on another computer. Is there anything I can try in the meantime?

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.
