How to capture USB packets please?

edit

Thanks for the info, Graham, it's certainly helped I hadn't twigged that it's a two-stage process - use USBPcapCMD to capture the packets to a file then use Wireshark to display them. I'm using the latest Wireshark (2.4.2). tshark shows only the wired interfaces, as shown at start-up. Cheers

It is not intended to be a two-stage process. Normally *shark should call USBPcapCMD.exe in extcap mode and show you each USB root hub as a capture-able interface just as you expect. So if you can capture using USBPcapCMD.exe run from the command line but not from *shark, something is wrong.

So if this is the case, it is a sufficient workaround but not what was intended.

OK, there does seem to be a problem with my installation then, since the USB interfaces aren't offered in Wireshark. What can I do to help sort it out?

Does your `C:\Program Files\Wireshark\extcap` directory exist and contain a copy of `USBPcapCMD.exe`? (If you have installed Wireshark elsewhere, use that path of course).
