Serial to usb converters can be a real PITA as you are finding out. I have had luck with plugging in the usb by itself(letting the computer recognize it) then plug in the MSD.

I have had the best luck with the one from Radio Shack. Don't know why but it seems to work the best.
MSD box is installed in the car, both red wires are connected and it's operating in place of the factory CDI box (red light on the box comes on when the car is started) so I'm assuming it's not a wiring issue. Still, I should ask; could the engine start and run, and the MSD light come on if there was no power to the 12V switched (smaller of the two red wires) source?

The second USB adapter I tried was recently returned to Radio Shack, replaced with the one MSD seems to favor.

I'll go back and try various orders-of-connection and see if that helps.

Thanks for the suggestions.
