Description

What¡¯s a USB Hub and Why Do I Want One? A USB hub is a device that expands a single Universal Serial Bus (USB) port into several so that there are more ports available to connect devices to a host system.If you¡¯re not familiar with USB hubs, don¡¯t worry. A USB hub is to USB devices as a power strip is to electrical devices: you use a hub to split the capability of one USB port on your computer among many devices just as you use a power strip to split the electrical power from a single outlet in your home or office among multiple electrical devices. There comes a time in everyone's life when they look over their desk for a place to plug in their phone, a new wireless mouse, a portable hard drive, or some other peripheral, only to discover they're out of USB ports. When that happens, it's time to buy a hub. USB hubs come in all shapes, sizes, and types. Not only do you need to pay attention to features and specifications (despite how simple a USB hub might appear at first glance) you also need to be aware of the existing hardware on your computer (be it a desktop or laptop) in order to get the best performance out of your the hub. You can spend a ton and get a high-end USB 3.0 hub with lights and tons of powered ports, or spend next to nothing on a portable USB 2.0 hub you can take with you in your pocket or your go bag.
