I've downloaded and installed Wireshark to snoop 4 USB ports. I've also imported the USBPcap CMD file in to the wireshark extcap directory. However, when I start up wireshark, I only see one instance of a USB device. I'm able to snoop different USB ports on the same USB port in wireshark, but I'd rather have three separte ports listed so I can get an idea as to which one I'm looking at. Any ideas how I can modify this setup? Also, is there a dll file I need to download?
One last thing, I've also downloaded WINPcap. Is this necessary?
