The USB Link Visualizer allows operators to identify the state of USB link and its speed. The dongle is used between a USB host (Type A receptacle) and a USB peripheral device (or cable). It helps the operator visualize and troubleshoot basic USB operations when there is uncertainty about the link performance. Since the USB protocol is designed to fall back to lower speed rates if the bus responses are inconsistent, whether on host or device side, due to signal integrity issues, bad cables, or bad (worn out) connectors, the USB Link Visualizer allows quick assessment of link issues before the need to deploy much more expensive USB protocol analyzer equipment . The Visualizer is designed to be non-invasive to USB signals as much as possible.
