pcap files fully automatically, without any manual pre-processing, you'll have to include analysis of the enumeration phase or some heuristic into it. If necessary, you can save only frames matching the display filter into another. In the Capture menu, you will need to select the USB option. Once Wireshark is installed, you can launch the program and click on the Capture menu. To capture USB traffic with Wireshark, you need to first install the Wireshark software on your computer. So your best bet is to run USBPcapCmd.exe before inserting the devices you want to capture, and to analyse the enumeration phase to identify the bus and device IDs you'll use in your display filter expression to show only frames to/from the devices you are interested in. Wireshark is a free open source packet analyzer that can be used to capture USB traffic. So if you have two USB keyboards and insert them in different order after restart of the computer, their USB addresses differ between cases. The mapping between physical USB ports of the computer and/or of external hubs and the USB address () is dynamically created during the enumeration phase. (To make things even more confusing, a USB device connected to the very same physical port is seen as connected to one root hub if it is a USB 1.1/2.0 device but as connected to another root hub if it is a USB 3.0 device). First, check if you belong to the wiresharkgroup with: groups USER To add yourself to the wiresharkgroup, run the below command, then logout and login. ![]() When running USBPcap from Wireshark or tshark, each root hub is offered as a separate extcap interface. Capturing USB traffic on Linux is possible since Wireshark 1.2.0, libpcap 1.0.0, and Linux 2.6.11, using the Linux usbmon interface. ![]() When running USBPcapCmd from command line, it is mandatory to choose a root hub. The only thing resembling a capture filter to be available in USBPcap is the choice of root hub on which to capture. The tree topology of the USB allows to connect several hubs in a chain, and there is no static mapping of physical ports of the hubs to USB addresses of connected devices.
