It should never be necessary to connect two USB host ports, not two USB client ports. Indeed, not only not necessary, but most unwise.

There is certainly no mainstream use for them. I doubt you'd see such adapters in Best Buy or Walmart. But tech types do encourage innovation, so who knows what some hackers have cooked up a need for.
