For what i am working on, it will take some time.

IMHO, Yes. And there wouldn't be any adapter2 or adapter2/xyz, if
adapter1 (the same case for adapter0 too) doesn't exist.
Therefore if adapter1 doesn't exist, there shouldn't be any need to
probe for adapter 2,3, etc, assuming that adapter0 is the only 1 card
that is present.
