OK, so this is what i have gathered.
You can connect to your MS2 just fine with a serial cable connected to the stim.
You can connect to the MS3 just fine with the serial cable wired into your car.
You _CAN NOT_ connect to the MS3 via usb no matter on the stim or in the car.
You _CAN NOT_ connect to the MS3 via serial/usb connector in you car.
This does not matter if the computer used to connect is different.

It is a new build, but I bought it from MSLabs, so it's all pre-setup. And I have connected to it when it's plugged into my car and when using a USB>Serial connector.

As with all things, never rule out the possibility that the simplest fix is always relevant to a large problem.
