Hi Roger,

WinPcap is still not able to capture packets coming from a MBIM device (due
to the various reasons explained by Evan and Guy a few months ago), but if
you use USBPcap (found here: http://desowin.org/usbpcap/ ) with a
development release of Wireshark (found here:
http://www.wireshark.org/download/automated/ ) you should be able to
capture MBIM IP traffic (and MBIM control packets also) directly at USB
level.
The setup is not as straightforward as clicking on button in Wireshark GUI,
but by following the small tour found on
http://desowin.org/usbpcap/tour.html you should be able to get things
working rather easily.
That's the best alternative method we can offer for now while waiting for a
more official support by WinPcap.

Best regards,
Pascal.
