With that accomplished, adding a new device was as simple as plugging it into one of the ports on the hub. The ADS hub offers a manual with pictures and detailed instructions, but only a one-year warranty. If you already have USB ports but want more, an external hub is the easiest way to add them. For those serious about USB, seven-port models are available from these and other vendors. Each of the external hubs came with an external power supply and status lights.
Installation is quick and painless for all.
ADS provides a power-on light and LEDs for each port. The Entrega 4 Port USB Hub has the smallest footprint and a three-year warranty. Keep in mind that USB is not designed for speed and that it is an immature technology that still needs some kinks ironed out. Be aware that when you're attaching new USB devices, bandwidth can be a constraining factor. USB shares its 12-Mbps pipeline with all the devices hooked to it, and it runs data over the computer's PCI bus, draining CPU resources.
