USB Analysis Features of USBlyzer

USBlyzer is a featured software-based USB analysis tool that enables you to view USB device descriptors, capture and analyze USB devices activity in real time, save captured data for later protocol analysis. USBlyzer not only shows you a raw hex dump of the data that was sent to or received from a USB device. USBlyzer looks at that data and decodes it into human readable form. This feature greatly speeds up usb analysis efforts. Simple to use, this USB analysis software is the ideal companion for anyone who is developing USB device drivers and software.
