You have many USB devices that you want to plug on to your computer. But your computer only have 4 USB ports. And all of them been used by your keyboard, mouse, usb pendrive and your printer.
But you want to transfer pictures from your digital camera, you need USB port. You want to use microphone to have a live chat with your Yahoo! Messenger buddies, you need USB port. You want to use webcam, you need USB port. All of them need extra USB ports.
How about if you have 1 USB hub with 31 USB ports ready to use? I am sure you will not have any problems with your USB ports anymore. 😉
But how much power does it need to supply this USB hub? :-w
