Comment # 2 on bug 1129496 from Ancor Gonzalez Sosa

I suspect this is a consequence on how activation works, every time we activate
a new device everything is re-checked (since you can have an inactive device
that, after activation reveals another activated device that, if installed at
the same time than another reveals just another, and so on, and so on).

I would have to check, but I suspect that the activation of the third and
fourth devices was what brought back the question about the first and the
second. We need a smarter mechanism here.
