Hi,

This is because the USB CDC drivers are enumerated correctly, and the serial number of the device itself is then reported back to the PC via that specific usb descriptor.

[quote user=""]So i tried opening the J-Link Commander V8.12f for arm64, and the device cannot be found;[/quote]

This seems to require different handling unfortunately:

Do you have a x86 device available which you can run the above sequence on?

Kind regards,

Håkon

Hi Hakon,

I already tried it, this does not work. the device is recognizable by nRF connect.

What does seem off is that it uses 3 different COM ports to communicate with the device.

Hi,

The firmware running on the SEGGER ODB (on board debugger) can contain an older version, which requires the use of SEGGER's legacy usb driver. Could you check this box during jlink installation and see if it runs as expected afterwards?

Kind regards,

Håkon
