Jlink V6.16c does not recognize the sniffer when attached to a USB port.

Jlink immediately reports it cannot find the attached.  The system is Windows 7 pro.

What is the sniffer that you are talking about ?

additionally mention the name of the board and the board version you are using .

if you are using Adafruit products as a sniffer , note that they do not have the jlink emulator ic on their boards and the jlink behaviour that you see will be expected.

Edit:

Added information on the Adafruit board:
The adafruit board should work with the nRF Sniffer v2 which integrates directly with Wireshark 2.4.6 , you will not need to re-flash the firmware as the default firmware loaded on the adafruit board should work

David,  Yes I am using the Adafruit sniffer.  They direct their customers to the Notrdic sniffer site for all support.  Since Jlink cannot find the device them I am not able to update the firmware.  Catch 22.  Where do I go from here other than returning the device for a refund?
