USBview shows more ports than exist. Why?

While troubleshooting a misbehaving USB port on my Toshiba Satellite Windows 10 laptop, I installed the USBview utility for the first time ever. The port magically came back to life but I am curious: my laptop has 3 USB ports (2 of USB2.0 ,one of USB3.0) but the USBview screen shows seven USB ports. Why is this?

I only see 3. The USB hubs are the physical ports. USB technology itself can allow up to 127 devices daisy chained together via USB hubs (physical).
