Using zigbee2mqtt with a cc2531 sniffer

I have downloaded zigbee2mqtt to a windows 10 laptop. The laptop recognizes the cc2531 as a cebal device. The zigbee documentation states that configuration.yaml should be modified to give the location of the cc2531 as either COM3 or COM4, but modern laptops do not have COM ports. How do I describe the location with a usb port. The cebal location is given as Port_#0001.Hub_#0001. How do I enter this into configuration.yaml?

Did you flash the cc2531 with the zigbee2mqtt firmware ? It should show up as a comport if flashed correctly.

No I didn’t. Thanks Francis. It now registers as COM3
