Important information inadvertently left you!
I meant taking a USB log of the traffic of a Windows-based scan.
For WinXP, UsbSnoop is good, because I have a parser for that.
For later versions of Windows, I guess you could you use Wiresharp
with UsbPcap, looking at the output in Wireshark would work for me
too.
