Adding 4 Port USB Hub

  chas 16:42 24 Feb 2003

I need to increase the number of usb outlets by fitting a 4 port adaptor. I have been told by one supplier that I need an AC supply to power it. I was under the impression that it was powered by the computer. Just plug it in and couple up???
Any help pls.

I recently bought a 4 port powered hub that you plug into the mains, connect it to the pc and all the usb devices into the hub. I think the idea of a powered hub is to eliminate the hub drawing power from the pc's power supply. You can buy unpowered hubs but at 17pds for a powered hub!!!!!!!

You can buy either version - a 'powered' hub, which has an external power supply, or one that is self-powered via the USB port on your motherboard.

Powered versions are generally preferred, as connecting several power-hungry peripherals to a hub can cause supply issues with motherboards that barely supply the required 500mA.

Ultimately, it depends on what you plan to connect to the hub, and the quality of your existing USB connectors.

To be safe, I always recommend a powered hub.

Yes, Dodger148 is right. A powered hub simply relieves the load on the PC power supply by supplying power to the devices which are attached through it.

The one I've got (I can't remember the make) is powered, but you can leave the power switched off if your devices aren't drawing too much.

I prefer internal usb hubs just because they dont have to time share. When you have a single lead going into 4, the 4 are shared through the one connection. When you do heavy scanning, printing and digital photography this is really noticeable. However, if you only use one device at a time, you wont notice.

I'm not sure that I made it clear in my previous posting that I was referring exclusively to an external hub.

An internal hub connects via the PCI slot, which is where it draws it's power from.

Belkin do a good one
£19.99 down PC World 4 Port USB - Hub
They do a 7 or 8 port too but I cant remember which or the cost for it.

A powered hub is far superior to the non-powered variety.

It's important to remember that scanners should be connected directly to a USB port on the computer, otherwise you could have problems; the second USB port should be used for the four port hub giving an additional three ports for digital cameras, webcams etc.
