It may help to run your Windows instance not on bare metal but in a VM
(e.g. under GNU/Linux with KVM; or Xen; or maybe even just Qemu or
VirtualBox). I believe this should let you use the host OS to
inspect/sniff the USB traffic being sent between the guest OS and the
USB device. This sort of thing:

I wonder how
the Windows software communicates with the X5, though.
That's not obvious from the lsusb output. A reverse engineer might
need to intercept/sniff the USB traffic between the X5 and a Windows
host to figure that out.
I set up WireShark as it's reported to sniff USB. Under Linux I got
some packets. Under Windows I haven't made much progress yet but it's
early days.
