Abstract:
A method is described for capturing USB data traffic for a monitored device by a USB analyzer using a single USB host controller. It comprises the steps of: generating and storing an address and communication speed associated with the USB analyzer; reading a USB packet; discarding selected read packets based on the stored analyzer address and communication speed; and transmitting the remaining packets to an analysis computer.
