If laptop computers come complete with USB hubs built in, why is it that we would need external USB hubs? The beauty of an external USB hub is that it allows for the consolidation of a number of devices (including printer and mouse) into one hub allowing for efficient removal and attachment.

First things first, what is a USB hub? The quick answer to that is that is a device that allows for numerous USB devices (or Universal Serial Bus devices such as printers, flash drives, media players) to be connected to a solitary USB port on another hub or host computer.

USB hubs come in a variety of styles including the favourite form of a box (similar to a network hub in design) which are connected via a long cable. In the instance of a short cable hub, there is a six inch cable proving useful for busy ports.

What of a powered USB hub? This is a device powered by an external power source allowing it to supply to every unit full power. Hubs in general are either operated as self powered hubs or bus powered hubs – it’s a case of one or the other.

Unfortunately some powered USB hubs are not able to deliver enough power to a load on every port of 500mA. Some can go into shut down mode following an overload making power problems that arise difficult to analyse.

What of a bus powered hub? This is where all the power is drawn by the interface of the host computer. No separate power connection needed sounds good on the face of it until you discover that your devices require more power than it is able to deliver.

A switchable USB hub solves the problems that can arise in these incidences by switching the operation mode between bus-powered mode and self-powered mode. Included is a bus controller for receiving computer system signals via the serial bus. Signals are additionally received from the serial bus hub.

Where would we be without a powered USB hub? Without a powered USB hub, we would be frustrated and backed up with jobs taking uneccessary amounts of time than they need to. Offering convenience, time saving and all round efficiency, if you need to get ahead with a job, look no further than a powered USB hub.
