Connecting More Than One Device Under Test
USB analyzers are able to analyze traffic coming only from devices connected under them. If a device is connected above the analyzer, it will only register data packets coming from the host. The figure below shows an incorrect connection: the USB mouse is connected 'above' the analyzer.
The figure below illustrates how to connect correctly several devices under test. When the Frontline analyzer is used to capture data from multiple devices, this analysis must necessarily involve a USB hub. In this way, you can ensure that all the devices to be analyzed are, in fact, 'below' the Frontline analyzer. You should be aware that the analyzer will record all hub and devices traffic. Though it could result in a large amount of data, this volume of data will not cause inconvenience because the Frontline software's functions can filter out extra traffic very easily.
