USB Analyzer is a powerful tool for monitoring USB port activities on Windows. It enables intercepting, displaying, recording and analyzing data exchanged between applications and devices via USB ports in the system. The data collected is invaluable for efficient software coding, testing and optimization, and this tool is a must-have for development of software applications, USB device drivers or hardware. USB Analyzer provides a convenient view of all USB devices available in the system - either as a simple list or as a hierarchical tree. The software detects a device immediately once it is inserted in a port, and you can start monitoring the port™s activities right away in a real time mode. It is possible to initiate multiple sessions to monitor several ports at a time. The monitored data includes all outgoing and incoming data, as well as IRPs, URBs, IOCTLs that pass through a USB device stack. The collected data is presented either as a raw hex dump or a decoded human readable format. To view only relevant data you can apply dynamic filters and use convenient search feature. You can automatically switch between corresponding outgoing and incoming packages, there is no need to pair them manually. Collected data can be saved in a binary file and exported in one of the following formats - TXT, CSV, XML, json or HTML. This proves to be helpful if you need the data for later analysis. The application supports USB 3.0 devices and USB root hubs.
