usbsnoop is a small but very useful utility program which can sniff/monitor, and log to file, all data exchange between an USB device and its driver under a Windows OS environment.

There are actually several such, highly related, utility programs and derivative works that are often casually referred to by the name "usbsnoop". Though such usage is technically incorrect, it is understandable due to their somewhat confusing and intertwined developments. An attempt to differentiate between these different apps, and illuminate their shared history is provided below.

History

USB Snoopy was released, in April 2000, by "Tom and Roland" (from "wingmanteam.com"), as a small utility for monitoring a USB device's communications traffic under a Windows 98 environment (see archived webpage). The USB Snoopy release consisted of three parts:

  • a simple GUI program, SniffUSB.exe, to install and remove the filter driver
  • a filter driver, UsbSnoop.sys, that monitors the actual USB traffic
  • A debug viewer, dgbview.exe, was included to catch the output from the filer driver. (dgbview was written by Mark Russinovich from Sysinternals, which later went on to become a part of Microsoft)


Inspired by USB Snoppy, Benoit Papillault releases, in Mar 2001 usbsnoop v1.1, [1], which he describes simply as an "USB sniffer for Windows 2000".


Note: This section is still a WIP. The following bullet points currently serve just as reminders to expand upon some other development milestone points and/or history -- to be cont'd
