[obdgpslogger] Switching to Windows/Cygwin, can't get OBD data

Looks like taking these steps:
* installing the OBD software package that comes with the USB device
* Running the Windows program
Seems to have done the trick.
I know #2 seems like a Voodoo step, but I've noticed that obdgui can
sometimes not show data, or not start correctly the first time around, but
work well the second. So it's not unlikely that having another app speak to
the USB connector works.
Of course, I'm talking voodoo, and when people talk voodoo in my products I
tell them they're crazy.
