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.

Correct I should add when connected to the (different) car too).


Correct but it's via a Serial/USB converter, I don't have anything with a native serial port.

Correct, but on the stim, something is detected

No, I can connect via the serial port via a serial>USB converter when on the car

Correct.

hm... seems that maybe, just maybe the cable might be faulty. its worth a try. i know you are going to be looking for one to test. ill mull it over to see what i can think up. in the mean time, run portcheck.exe from here
http://www.msextra.com/doc/ms2extra/serial_setup.html

with the MS3 connected and report back.

Have tried port check on the stim, predictably it fails.

I can try it on the car at the weekend.

does this need the 12v pullup form s12c to work? im sure you have that...just brainstorming.

Good question, I've no idea. I'll check to see if its present or not.

If it is needed I suspect it'll be there, not often you hear of Rev missing anything!

Uh, sorry if this is a bit basic, but is this a new MS3 build?

Did you do the initial firmware install/flash before trying to connect with TS?

Just covering bases...

How pray tell would that be possible if you couldn't connect to it?

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.

Tried a different cable on the bench, it worked!

But as is the way with me, the old cable now suddenly works too. ******* weird.

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