Product Details
FTS4USB captures traffic between a PC and a USB device using the USB ComProbe II hardware, and transmits the data to the analyzer PC via a USB port.
FTS4USB can also analyze internal USB circuits by monitoring the data passing between the USB driver and the device driver inside the PC. The internal version is called Spy Mode and doesn't require any additional hardware.
Both hardware and software come together for one low price.
