USB protocol capturing, decoding, displaying, filtering, errors detecting and much more what cannot be done by others.
USB Monitor Pro is an effective and simple in use analyzer of USB traffic for Windows. It allows to monitor incoming and outgoing data of a USB device plugged into the computer.
USB Monitor Pro is a complete software solution, so you don't need any additional expensive hardware.
It's an indispensable tool for a developer of firmware and drivers for USB devices, expanding developer's arsenal.
USB Monitor Pro development is based on a long-standing experience in USB devices drivers development and you can easily make sure how much it's convenient and simple in use. Just choose the device and start monitoring.
No critical information will pass by USB Monitor Pro. INTERNAL_IOCTLs, URB packets and IRP packets of PnP and PowerManagement subsystems will be captured and displayed immediately. The monitoring takes place in both directions (from device driver to the Host Controller Driver and vice versa).

Format of captured data displaying is arranged to simplify data understanding as much as possible.
In spite of chronological ordering of captured information it's possible to get more detailed information (e.g. URB packet structure, hex-dump of packets carrying data) for every URB and INTERNAL_IOCTL packets at any time. Just click on a packet and you'll get it.

USB Monitor Pro analyzes captured traffic and allows to immediately find URB request (or INTERNAL_IOCTL) come out to the Host Controller Driver and also corresponding URB packet processed by the Host Controller Driver. You will see both packets at once to compare them and then to make a corresponding conclusions.
When the program works in this mode all you have to do to start monitoring is to plug a USB device into the computer. The program automatically starts monitoring the first plugged USB device.
Built-in search engine allows to find wanted information rapidly. Moreover, filtering mechanism allows dynamic hiding and showing only needed types of captured data causing automatical hiding of unnecessary packets.
Unlike other USB monitoring programs which don't allow to examine captured data while monitoring, USB Monitor Pro is totally free from this limitation. You can easily examine all needed information in real time.
Moreover, you can monitor several USB devices simultaneously.
Captured data can be saved to a file and then can be opened by the program for further examination.
The real professionals in USB communications have been developing and supporting USB Monitor Pro. The main goal we strive for is to help you to save money, time and probably nerves.
We want you not to waste your time on monotonous "digging" of protocols and data but concentrate your talent on your project working with the pleasure.
USB Monitor Pro is successfully used for software development, devices drivers debugging and analyzing of USB traffic. It's also a powerful tool for effective testing and optimization.
The program is successfully used for tasks like protocols analysis, reverse-engineering of USB protocols and functionality determination of third-party device drivers.
USB Monitor Pro is used by software developers, hardware engineers, IT support specialists, programmers, beta-testers, industrial control personnel, SCADA software engineers, science technicians, systems integrators, consultants, lab experts, university students.
