Unfortunately the Multisim Master database doesn't have USB hubs on those two models. However, please keep in mind that you can always create your own component that meets your requirement.
I do know that the 2 models in Multisim do not have USB. I also know that you can make models that fit your needs. Unfortunately I do not know how to make my own models so I was hopping someone has made a model or two and wouldn't mind sharing.
