Software analyzers are dependent on the timing precision of the host operating system which is thousands of times less precise than a dedicated hardware analyzer. With USB 2.0 protocol analyzer you may sniff the activity on any kind of USB, including the rising USB-C technology devices. The Beagle USB analyzers can provide accurate time stamping of USB traffic down to nanoseconds precision. Once you figure that out and capture the traffic, then its likely that it still wont dissect the application traffic as most dissectors dont support USB as a transport media. Switching between corresponding outgoing and incoming packets USBPCap does support capturing on USB interfaces, youll have to determine which of the interfaces listed corresponds to your USB to serial converter. Possibility to filter out the unnecessary information from analyzed data Possibility to add markers to the captured data displayed in the main GUI The 1s and 0s on USB are virtually meaningless. This isnt overly difficult but it isnt trivial either. You need to monitor the JK chirps to determine which direction data is traveling. However, there is only 1 set of differential signal lines. Raw hex dump and decoded human readable view of the data sent to or received from a USB device EXAMPLES Capture the USB raw packets on usbus2: usbdump -i usbus2 -s 256 -v Dump the USB raw packets of usbus2 into the file without packet size limit. USB is a point to point protocol between the Host/Hub or the Device. Real-time interception of IRPs, URBs, IOCTLs and data transferred through any USB device stack Interception, recording, display, and analysis of incoming and outgoing data between USB device and applicationĪll connected USB devices are displayed in a simple list or hierarchical tree view
