USBPcap can capture Windows USB transactions which Wireshark 1.10 or later can interpret: http://desowin.org/usbpcap/ Note, if you're used to WinPCap or usbmon capture integration with Wireshark this will be an adjustment. You have to run USBPcap from the command line to do the capture to a file, quit the capture, then open the file in Wireshark. I think depending on the options you pass to USBPcap you could end up with .pcap frames that are larger than Wireshark can handle (i.e., for a READ(x) transfer of 128 blocks).
