I am extremely new to this subject --I have done serial port stuuf, but
that was more than a decade ago.
USB seems quite a bit of different beast.

USBTrace, I mentioned in another post, talks about lists about a dozen
'Device Class Decoders' at this URL [ halfway down the page,
http://sysnucleus.com/usbtrace_download.html ] plus how to write a
vendor specific 'Device Class Decoder' [
http://sysnucleus.com/usbtrace_cd_vendor.html ].
If I need to go through all this, before decyphering the actual
information I am after, it seems I have bit more than I can chew ;)
The problems are going to start when the (Windows) driver contains
code that has to be downloaded to a microcontroller in the device.
Hmmm.. This device (Contour USB) installs a Java application --claimed
to be usable in Windows, Linux and OSX.
Would you say it is also installing a device driver too?
I think this device is some form of mass storage device; but I am not sure.
How can I tell whether it does install a device driver also --in Windows
platofrm.
You could always do what I do when reverse-engineering serial comms:
get the file from the capture device, convert it into text in a
convenient format, and then massage it using a sequence of Perl filters.
USBTrace seems to be able to help in filtering and/or turning the data
exchange into an organized blurb [it darn well should; for that price.]
