You may also use Wireshark capture and analysis tool. To capture all packets from a specific host on the network: Tcpdump: verbose output suppressed, use -v or -vv for full protocol decode To capture all packets on the WAN (the below assumes that interface eth1 is the WAN interface): tcpdump relies on libcap, therefore it can produce standard pcap analysis files which may be processed by other tools.
It may be used to capture packets on the fly and/or save them in a file for later analysis. Dont forget to wrap the address inside ' '. Then apply this filter usb.idVendor The-vendor-ID and usb.adrr 'The address you got'. Get the destination address that the PC uses to communicate with your device, Its usually something like 2.1.0. Tcpdump is a network capture and analysis tool. This filter wont get you all the traffic of the filter so you have to add another filter.
