sorry about that, I manage to export once in xml format, but do not 
manage anymore???
I tried also to use  sniffusb-0.13, but the debugger (dbview) failed to 
connect (can not contact driver???). Maybe because I am using windows XP 
  Home, does someone know a workaround? Another usb sniffer?

I will try to test this to see if we can get some informations...
