Musocity, I see the point you are trying to make. It might or might not work, it would require 4 items (2 cables / 2 adapters). In theory it should, but it is a one strange way... Also, not sure if that kind of (dual hub) connection will go well with iOS, as it is very selective. The piece I found was tested with ipad>PC.

I do appreciate thoughts, but it seems an uncommon scenario / and very uncommon all in one device.
