Can TestComplete sniff ethernet / USB traffic?

I had to do something similar but for web traffic using Fiddler. I actually had TestComplete start Fiddler in recording mode before my tests started, then when the tests were finished I had Fiddler export the logs as text.



Then I could load up the text file in TestComplete and parse as required to verify certain parts of the test.



One possible option for you if TestComplete doesn't allow this natively. I'm sure you can export the traffic from Wireshark in some format.
