USBlyzer is an application for sniffing and analyzing activities of USB ports in Windows. It allows monitoring data exchanged between devices that interface via USB ports and applications. You can search for specific information or use dynamic filters to view only relevant data.
USBlyzer is a handy tool for those who develop software applications, design hardware drivers and test system configuration. However the application is quite expensive, and if you are not ready to spend a lot on such a tool, read on – there is a USBlyzer alternative at a much more affordable price.
USB Analyzer by Eltima Software
USB Analyzer is another tool for monitoring USB ports in the system; it is efficient, compact and easy-to-use. The data it collects allows detecting potential problems immediately and thus proves to be critical for application debugging.
Advantages offered by USB Analyzer:
Monitor port activity
Once a device is plugged into the system via a USB port, the app can start sniffing its activities immediately. The real time mode allows identifying and correcting potential problems from the very beginning.
Collected data can be viewed as raw hex dump or as a decoded human readable text, so you can analyze the data while monitoring. It is possible to run several concurrent sessions at a time for monitoring multiple ports.
Capture, save and export data
USB Analyzer is capable of monitoring all kinds of data that goes through a USB port, including IRPs, URBs and IOCTLs. There is a raw data view visualizer that enables displaying raw packet data flow. The application does not require much interference from your side, so you can leave it running in the background for as long as you need to.
Collected data can be saved in a binary file for later analysis or exported in a number of formats – plain text, CSV, XML or HTML.
Display monitored data
Each data packet is displayed with brief info, as well as detailed information about it. The former is displayed on top of the app’s window, while the latter is at the bottom – choose between Command View and Data View (Hex and ASCII).
Toggle between outgoing and incoming packets
USB Analyzer allows you to switch between outgoing and incoming packets automatically with the help of a button. Not having to pair data streams manually can save you a lot of time and effort.
Search and filter data
You can search collected data for specific information, the search criteria includes inner content of a URB packet. It is also possible to use dynamic filters for viewing only relevant information.
