USBTrace

USBTrace is an easy to use and powerful software analyzer for the USB bus and the devices connected to it. USBTrace can monitor USB transactions happening at USB host controllers,
hubs and devices. USBTrace is a 100% software product. It is especially suited for inspecting host side USB protocol. USBTrace supports Windows 2000, Windows XP and Windows 2003 Server operating systems.
USBTrace is a non intrusive analyzer since it does not use any filter drivers to monitor USB bus activity. For the same reason USBTrace does not disturb the PNP system and is capable of logging all USB transactions during device enumeration and removal.
