It runs smoothly, processes monitored packets in real-time even on high data rates (up to 20 Gbit/s). This Freeware USB data snooping utility requires no additional hardware or cables to operate. Our USB monitoring program may be an excellent alternative to hardware analyzers because it intercepts all Windows API function calls which are transferred between USB applications and device drivers, parses transmitted packets and shows all captured data in a several convenient forms, which is virtually impossible for hardware solutions due to their low level view. All Windows desktop/server 32-bit and 64-bit platforms starting from Windows Vista are supported.
