May I ask how you did that? I'm searching a usable but not very costly
USB monitoring thingy for Windows(XP).
I used USBTrace [ http://sysnucleus.com/ ]. It's not at all cheap [195 USD].
What do you use for this sort of thing?
For a small controller built using an ATmega64 and the abandoned Philips
PDIUSBD11 I did it on low level. The operating system gives me a raw
device, /dev/ugen0 on FreeBSD, and I have translated a small subset of
the USB headers. These are used to talk to the device sending user
requests implemented by the maker of the small controller board.
I can show some code snippets if you like.
I am using Windows (will later port to *nix or --if I can-- to OSX when
I release it as freeware)
USBTrace exports in XML format with content such as below [this a short
<g> sample of 200,000 lines I got for one session alone]
I apologize for dumping on you this, but I thought you might like to see
what the USBTrace output looks like too.

I believe all those capitalized labels are constants.
What the others are I have no idea yet.
I have a similar problem with another type of hardware, but the USB
analyzers (hardware) or sniffing software are very comfortable, they do
on the fly protocol decoding and the like, but those have their price.
And this price is amazing. ;)
In my case, health considerations took precedence, I'm afraid.
