[5/5]: Rick Gayheart, 06/14/2014
I was having an issue where my laptop could not talk to the QH with the engine running, and the engine did not run right with the USB plugged into the laptop. The Optoisolator solved this. The Optoisolator requires key on to talk to the QH. However you can still plug into the regular port and download to the chip, while on the bench. Note plug to one port or the other never both at once. So, in my opinion you give up nothing. At ~$40, it is worth just ordering it and having your QH prepped all in one shot. It sure could save you a couple weeks of frustration.
