Example USB Bus Analyzer Catc Traces | Cypress CY4672 specification

Bridge

5.4.5Example USB Bus Analyzer (CATC) Traces

Figure 5-17below shows the USB data transmissions between the bridge and the host PC captured with the USB CATC Bus Analyzer. In this example, the Right Shift + ‘g’, ‘h’ keys were typed followed by the ‘Volume Up’, ‘Volume Down’ keys. Note the keyboard regular key reports are sent to the PC via the endpoint 1 while the Multimedia key reports are sent via the endpoint 2 with Report ID 2.
