The program installs a filter driver between the USB host controller driver and the device driver and then intercepts all USB Request Blocks (URBs), displaying them to the user in an easily readable format. This USB sniffer helps in developing, debugging, testing and analyzing devices, their drivers, and other software/hardware solutions that exchange data using USB communication protocols.ĭownload this Free USB Sniffer and trace USB communications in seconds. Paid version also supports USB data recording (USB data logger function), sending packets to USB HID devices in response to triggered events and allows you to automate workflow with scripts (written in JavaScript or TypeScript). It includes browsing, searching for specific data patterns and exporting features. The free version provides all the basic tools for convenient tracing and exploring captured USB data. Paid version also supports filtering by parsed protocol fields and provides you with a lot of custom filtering options. Free version supports filtering by USB endpoints and requests. It allows efficient USB protocol analysis for High Speed USB 2.0, SuperSpeed USB 3.0 and SuperSpeed+ USB 3.x communications.įor the best user experience, our product supports data filtering. It runs smoothly, processes monitored packets in real-time even on high data rates (up to 20 Gbit/s).

This Freeware USB data snooping utility requires no additional hardware or cables to operate. Our USB monitoring program may be an excellent alternative to hardware analyzers because it intercepts all Windows API function calls which are transferred between USB applications and device drivers, parses transmitted packets and shows all captured data in a several convenient forms, which is virtually impossible for hardware solutions due to their low level view. All Windows desktop/server 32-bit and 64-bit platforms starting from Windows Vista are supported.

This software-based USB protocol analyzer allows you to monitor the data transferred between USB applications and devices connected to your computer via USB interfaces. Free USB Analyzer is a non-intrusive software USB sniffer and protocol analyzer for Windows.
