USBlyzer description
USBlyzer is an easy to use software USB protocol analyzer for Windows

USBlyzer is an easy to use software USB protocol analyzer for Windows, which provides a complete yet simple to understand view for analyzing USB Host Controllers, USB Hubs and USB Devices activity.

With USBlyzer you can view detailed information about all USB devices and their child components.

USBlyzer allows you to capture, decode and display important information such as URB requests and related structures used by USB drivers, IRP used by PnP subsystem, kernel-mode and user-mode I/O requests used by USB client drivers and user-mode applications.

USBlyzer can be successfully used for application, device driver and hardware development and can help you test and troubleshoot software and hardware.
USBlyzer is a complete software solution, so you wont have to install any additional hardware or software.

Youll find USBlyzer extremely useful for understanding how system-supplied and vendor-supplied USB device drivers communicate with the USB driver stack.

Here are some key features of "USBlyzer":

· Completely customizable interface with docked windows and user-defined screen sets.
Viewing
· Display all plugged USB devices in a hierarchical auto-refreshed tree-view.
