Power commander 3 not working

[Mustang]

I used the latest software, from the site as the pc didn’t come with a disc. Used a ubs lead - they are all the same aren’t they? What I can’t find out is what the firmware is in the pc, cos I can’t talk to it! I said to the seller, even if it worked on the bike, I’d need to change the map if I wanted a custom one or if it was sold on and used on an R1 or something, so it’s no good to me.
