Comment 5 for bug 459512

This patch is just the inverse of the previous one - if more than one device is present, just select the first one seen.

I'm going to go with the other patch since it's closest to what we were doing before, however I don't have strong preferences here. The main reason we went with the last busid before was for the use case where there is an on-board video chip, and the user has stuck in a second card that they'd prefer to be used. However, I think in these cases there is always going to be a primary device, so I don't think it is a relevant consideration any more.

Anyway, I'm posting both patches here and soliciting feedback on which would cover more cases in practice.
