 OVERVIEW

   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 won't
