Explain Non-powered vs. Powered Hubs?
A non-powered hub is a hub that does not use a power supply but instead gets its power from the computer’s USB port. Most external drives require more power than this method can provide, and therefore will not be compatible with this type of hub. A powered hub uses an external power supply (AC adapter) and can therefore provide full power to the USB devices that are connected to it. External hard drives that use bus power are generally only compatible with powered USB hubs.
