Free USB Analyzer Overview

Free USB Analyzer is a non-intrusive software USB sniffer and protocol analyzer for Windows.

Using this USB Analyzer you may capture and display any traffic passing over USB connections of your computer. Captured communication data raw binary format is parsed and decoded into a human-readable form, allowing you to review the exchanged data and perform effective forensic analysis of transmitted data packets.

The key feature of this Freeware USB logic analyzer is its ability to process monitored packets in real-time even under high traffic load. Together with other powerful features of this Free USB explorer and analyser utility it makes you able to explore and trace USB requests of all modern devices and applications, which are compatible with Hi-Speed USB 2.0 480 Mbit/s and SuperSpeed USB 3.0 5 Gbit/s dataflow.

How Free USB Analyzer Works

Program installs the filter driver between the USB host controller driver and the device driver and then monitors all USB Request Blocks (URBs), displaying them to the user in easily readable format.

This Free USB monitoring and analyzing software utility is designed for effective intercepting, capturing and decoding of communication traffic generated by any USB application passing through USB interfaces to and from devices connected to local or remote PC.

Free USB Analyzer supports advanced data filtering by URB type and USB endpoints.

Capturing and interactively displaying of data transferred via USB connections now made easy!

Free USB Analyzer Features

With our free USB sniffer and analyzer you can:

  • Monitor the bus traffic, decode and display the USB data, filter bus traffic
  • Intercept and view USB control transfers, interrupt transfers, bulk transfers and isochronous transfers
  • Parse and reverse engineer USB protocols, reverse engineer USB devices, drivers and applications
