By using USB hubs. Typical hubs provide either 4 or 7 more ports on the bus they are connected to while consuming only 1 existing port. There is a limit of 127 devices on a single bus with USB. This limit includes all physical devices and hubs (note: 7 port hubs are usually implemented as 2 hardwired 4 port hubs, so they count double). If you actually need more buses not just ports, you will need to add an extra USB card and install its drivers. Even though most laptops provide more than one USB port, don't assume these are separate buses. The laptop usually contains at least one internal hub to support these ports and any internal USB devices that it contains.

So yes, you can easily have that many ports off one system. Companies make 4 port, 7 port and even as high as 40 port USB hubs.
