Do you have Windows XP and at least Service pack 2 installed.
Service Pack 2 comes bundled with the neccessary drivers for USB 2.0
In device manager under the USB heading you must have:
PCI to USB Enhanced Host Controller
In the list.

SOURCE: Installing USB Hub
finsphan72's response is correct but you could use information one step earlier.
USB 1.1 is the older version of USB. USB 2.0 is newer and much faster. Your computer has hardware in it to talk to USB. Because it is an older computer, it has USB 1.1 hardware.
The USB hub is just a splitter. It lets you plug in several USB devices while only using one USB port in your computer. But it doesn't change the fundamental capabilities of your computer.
The only way to get a computer with USB 1.1 built-in to support USB 2.0 is to add a USB 2.0 card to the computer. This is an open up the computer and install a piece of hardware operation. It isn't very hard and it isn't very expensive, but it might not be something you are comfortable doing (and it is possible to mess things up - you probably wouldn't, but you could). Maybe this is an "ask a high school age friend for a favor" sort of situation.

Most USB hubs do not need an external power supply, except when a connected USB device draws more power than the computer/laptop USB port can supply. In this case an external power supply will need to be connected to the USB hub.
Normally this would be a 5 volt power supply, but make sure the polarity on the connector matches the power connector on the hub, check the label on the hub, sometimes it states to power requirements of the hub as well as the polarity on the connector. Normally the pin on the hub's power connector is positive (ie. +5V)

Try connecting the hub to another USB port. You may even connect this same device to another computer and check if that works. This will help isolate the issue better.
