Usbsnoopy compatible with libpcap and write libpcap files. May want to ping the snoopypro people and ask them if they can make Usbmon in linux uses to write wireshark compatible pcap files, you Since libpcap now has an encapsulation type for USB frames which TCPdump (download and install the latest tcpdump/libpcap svc version)Īnd also recompile your linux kernel so that it provides a pcap-likeĭescribes what you need to do to capture the usb frames on linux. To be able to capture the USB layer on linux you need a new version of
You must make it capture traffic on a much lower layer. To get something similar to what snoopy captured from your linux box Thats why there is no real relation between what Wireshark saw on
Wireshark you captured packets all the way up in the Ethernet layer. With snoopy you captures tiny frames in the Lower USB layer and with The Ethernet frames running on the virtual link layer provided by USB. With wireshark on Linux you were capturing not USB frames but rather So with SnoopyPro you are capturing USB frames. When used for EthernetOverUSB several layers above the USB layer is SnoopyPro is a USB capture tool and it captures the various layers of I think you are comparing apples to oranges here.
