Why do we use hubs?

Well the main reason is often to allow more than one device to be connected via a single USB port. This makes more use of the ports available to you and allows for a greater number of USB devices to be connected to your system.

To use this hub at its full specification you will obviously need USB 2.0 already on your PC. If you do not, then you will still be able to use the stylish hub albeit at the speed of USB 1.1 specification.

My main reason for using hubs is that they stop the need for having to fumble behind the main tower to connect to a USB port, or allow you to extend the distance to the port and place it within easy access on your desk.

If you are a Mac user then this is fully compatible with your beloved Mac and I am sure it would blend in nicely with which ever version of ibook/mac you have.

Well you don't have to worry about the hub being discrete in size that's for sure. I know hubs can be tiny nowadays but that isn't always a good thing as they can easily be knocked as they do not have any weight to keep them sturdy and in place.

Comparison next to a Nokia 7250i

This Enermax hub is defiantly compact and sleek. The sides of the case are made from plastic and the main surround is brushed aluminium. On the main side of the hub are four USB connectors with a small plastic cover above each one which conceals a LED to indicator when the port is in use and being accessed.

The rear of the unit has a small DC 5#V connector in which you can connect the hub to use the AC adapter which is supplied. Also a small USB mini B connector is near the adapter connector.

Using the hub:

As I have already mentioned to obtain the best use from the device you will need to have a PC or Mac with a USB 2.0 compatible chipset. The easiest way to check this is to view Device Manager > Universal Serial Bus Connectors, here you should look for an entry like USB 2.0 Root Hub, USB 2.0 Host Controller.

Otherwise it is likely that you have the original USB 1.1 standard which will allow you to use the device but at a lower speed.

The device is small and highly portable and as you have seen from the pictures the unit is smaller than the average mobile phone, so it can fit into your pocket discreetly.

Using the device on several machines was as expected and easy practice and took just a couple of seconds for Windows 2000 / XP to detect the device and assign it a drive letter you could then connect the desired peripheral to the unit.

With or without the adapter:

Depending on who you talk to people say you should always run a hub from the mains. I personally think that is wrong. There only time I would use a hub connected to a PC is if the specification of the PC is low and when the accessing of devices connected is causing the system to become sluggish.

The main reason is it depends on the device if a ADSL USB modem is connected it will run via the hub and PC, however as the modem is a device which will be constantly working to avoid potential power and slowness issues I would connect this type of device directly to a PC based port or via a mains additional power supply.

To connect the common devices such as mice and USB drives then the hub will perform perfectly well on its own. It is however worth making a point that other vendors do not include an AC adapter.

Verdict:

Hub In Use with two Memory Sticks

These types of devices result in limited scope on what to say as they are small and have limited functions and parts. The hub wins points for being a sleek and clean styled product with the ever popular brushed aluminium casing which finishes it off well.

If you're looking for a hub then this should be at the top of the list.
