The sample capture is available at the Google code: sample_2013_04_10.pcap You should see the packets allongside with their description. Once started, open the pcap file you have created in Step 2. Step 3 - analyse the dataĪfter you’re done collecting data, press Ctrl+C and start Wireshark. In this example I have simply started the X-Edit software that controls the DigiTech RP250. Now it is time to use the device in order to get packets captured. We will be capturing the Root Hub that showed the two Hubs connected to it and an composite USB device (it is actually DigiTech RP250). (A careful reader will notice that they can skip the restart part: all that required to get the descriptors in the capture file is to reconnect your device after capture has started.). Now you can run the USBPcapCMD.exe again and enter your desired output file name. Please disconnect the device from your computer - this will allow USBPcap to capture the USB descriptors needed for analysis in Wireshark. So now you know which of the Root Hubs available in your system you want to monitor. If for any reason you can’t see the list of connected devices make sure you have the USBPcap driver installed and you have restarted your computer after the installation. You should be presented with something similiar to the picture below. In order to do so, launch the USBPcapCMD.exe that is stored in the installation directory. The first step is to connect the device you want to sniff the traffic and identify the Root Hub this device is connected to. Step 1 - identify the Root Hub you want to monitor If you feel the information provided there is not complete (it doesn’t cover your case), please describe your problem on the USBPcap mailing list. Each of the steps contains short description of what should happen and in some cases gives tips for troubleshooting. This short tour assumes you have installed the latest version of USBPcap and Wireshark 1.10.0rc1 (or newer) and rebooted your system.
