No. I'm not sure how the number gets assigned but it's supposed to be
unique. So that if you plug a new device into the machine it gets
assigned a new pXpY set of numbers. Usually it is p1p1 and p1p2 for the
LOMs, but after that I have seen just random numbers. I don't really
know where it gets generated.
