20120246348 | METHODS FOR ANALYZING USB DATA TRAFFIC USING A SINGLE USB HOST CONTROLLER - 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. | 09-27-2012 |
20100049880 | Circuits and Methods for Reliable Automatic USB Speed Detection - The Universal Serial Bus (“USB”) 2.0 Specification defines three speeds of communication for its bus, and each has its own signaling characteristics. Due to the uniqueness of each speed, PHYs must be placed in a separate mode for each signaling rate. Although USB devices may know its communication speed, a general purpose USB analyzer must be able to analyze all USB communications. Rather than force the user to manually set the operating mode of the analyzer, this invention describes circuits for automatically and reliably determining the monitored USB communication speed. | 02-25-2010 |
