A non-powered hub does not provide the proper power, but is still useful for USB devices that provide their own power (some printers, some cameras), or those that need very little like thumb drives.

"Hub and spoke" is a term in air transportation to describe a common method for an airline to organize their flights.

When flying from one city to another, you will typically have a connecting flight through one of the airline's hubs. This system can also be implemented with other forms of mass transit, and cargo transportation.

Pen drive recog as unknown device?
In my experience, devices often do this when they are not self powered and are plugged into a usb port which is also not self powered like a non-powered usb hub. The computers usb port puts out a limited amount of power so when the device can't fully power itself windows sees the hardware but can't figure out what it is because it never gets the usb id (or another variant I've had is that it keeps detecting that I've added and removed the device before windows can get a lock on it) Hope that helps
