Replying to myself..
My ELM327 won't work. It's too slow and doesn't support the passthrough.
What are the differences between these ?

This is great - or seems like it. I need to find a WinXP driver for my old ELM327 usb adapter or buy a new cable.
One note - I had to change some settings to get the VM to boot in anything other than safe mode. It would either crash or hang at the XP loading screen forever.
I changed the audio...
