Link: Sniffing USB traffic with VMWare
Sogeti has released a Ruby script that will convert VMWare captured USB traffic to the PCAP format, so it can be easily parsed with Wirshark or other tools.
VMWare offers the possibility to dump any usb traffic at the lowest level to a dump file. We’ll describe here how to activate this feature, and additionally publish a script to convert the dump file to the PCAP format, suitable for use with wireshark.
Another similar tool is called Virtual USB Analyzer, and it can provide a nice parser and visualization for VMWare USB logs.
