These days I don’t have a dedicated Windows box, but I do have a Windows 7 KVM virtual machine. I was also hoping to sniff the traffic to see how to drive the voice side of things. Recently I wanted to do a firmware upgrade of a ZTE 3G modem dongle, partly to provider unlock it and partly to try and enable some voice functionality. When I first wanted to reverse engineer a USB device that only had Windows drivers the “easy” option was to take a Windows machine, install usbsnoop on it and capture the traffic as a bunch of verbose text files.

However hopefully these notes will remind me enough next time.)

(This is something I did a few months ago, and I really should have noted down all the details then so I covered everything.
