Mobile devices need many processing integrated circuits (IC) to handle the diverse functionality demands of their users. A typical smartphone has a communication processor, an application processor and a power management IC, all needing to share a single USB port and to communicate at high speed USB data rates of 480 Mbps.
This paper, which originally appeared at EE Times Europe (Analog), compares and contrasts different solutions that can be applied to this problem, ranging from a USB hub to a simple analog switch.

True, this is a very good paper discussing about using efficiently multiple services on single USB Communication Chip. It is in deed a very good article for designers using single USB port for connecting many different parts in the design.
In fact USB interface has changed the way Personal Area Network, think of the days when we were trying to interface devices using PC Serial Port the and the problems we were facing. Those days are now gone due to USB Developments.
