Attached file is USB traffic recorded and saved into pcapng
file.
I used Wireshark to to extract the data sent thru the medium. Then I’ve combined the data to one file, which turned out
to be wav
file (ok, I knew it’s a wav from the first moment when I saw the data in Wireshark).
Once played, it sounds like a chirping. Without better idea I’ve used Sonic Visualizer to take a look into the spectrum.
Yup, it’s the flag I was looking for.
