The problem is solved, I just ignored the prompt and everything worked as it should, guess this is how it feels like to be stupid
The software is dedicated for diagnostics on a radio receiver for an industrial remote control.
I don't use the PCAN-USB very often so I might not remember it correct but shouldn't I see a COM port for the device in device manager? at least the software I intend to use prompts me for it...
I get the "PCAN-USB" under "CAN-Hardware" in the device manager but nothing under "Ports", no warnings ...
