You might need to upgrade you graphics card.
USB 3.0 is the newest connection port upgrade, arriving on the market in 2010.
The cable port connection is far superior to the USB 2.0 port, as it is able to transport up to 5 gbps (gigabits per second), instead of the previous version's max speed of 480 mbps (megabits per second).
However, most computers do not yet have this connection port installed, in which case you are left to upgrade your own computer system to the newer, faster connection method.
Turn off your computer, then disconnect all of the cables running into the computer.
Remove the Phillips screws from the back side of the computer.
WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

Only work inside the computer case when the power has been switched off and disconnected. Never open the power source.
Some of the below steps recommend removing physical parts within the computer.
While in the computer it is highly recommend that you be aware of ESD and its potential hazards.
This unlocks the case, allowing you access to the interior of the system.
Slide open the computer case.
Inside the middle is a longer circuit board.
This is the motherboard of the computer.
On the back side of the motherboard, facing the rear of the computer, are PCI card slots.
These allow you to install additional hardware onto the computer.
Slide the USB 3.0 connection port into one of the open PCI card slots, then push down the plastic levers along each side of the slot to lock the card into place.
Close the computer cover, then tighten the Phillips screws and reattach the cables.
Power on the computer, then insert the driver installation CD into the disc drive of the computer.
Once the installation wizard loads, follow the prompts of the wizard to install the drivers.
Restart the computer once finished and the USB 3.0 connection ports are ready for use.
Compatible graphics cards for Gateway Computers
Just as a processor handles data and a sound card outputs sound, your computer's video card is responsible for processing graphics and displaying them on your monitor.
The video cards manufacturers build into computers typically have enough power for the average user, but it may be necessary to upgrade your video card for better performance in games or graphics heavy applications.
Understand which types of video cards are compatible with your Gateway computer and learn about all your options.
PCI Express Graphics Cards
Many newer Gateway computers have a Peripheral Component Interconnect (PCI) Express slot in which you can add any PCI Express compatible video card.
These devices range from budget cards suitable for everyday tasks to high end models for gaming that cost hundreds of dollars.
AGP Graphics Cards
Older Gateway computers likely have an Accelerated Graphics Port (AGP) slot for AGP compatible cards.
The AGP bus provides sufficient bandwidth for high performance graphics cards, but the technology is no longer in use and AGP cards are difficult to find.
PCI Video Cards
Nearly all Gateway computers should have at least one PCI (Peripheral Component Interconnect) slot regardless of age.
This slot has enough bandwidth to support a wide range of peripherals like sound cards and modems, but is not suitable for high end video cards.
You can find a number of low and mid-range cards for PCI slot computers, however.
USB Video Cards
USB video cards are also compatible with Gateway computers sporting USB 2.0 or USB 3.0 ports.
These external cards sit outside the computer and allow you to connect additional monitors to your system.
They are a good option for people who feel uncomfortable working inside computers.
How to buy a video card
Upgrade My Video Card on My Gateway Desktop
Gateway desktops are affordable computers, but they often do not come with top-of-the-line video cards.
Computer games may run slowly or not at all on your Gateway desktop.
One way to solve this problem is to upgrade the video card.
Video cards come in PCI, PCI-E and AGP interfaces, so you should be able to find a video card upgrade no matter what Gateway desktop model you have.
Click "Start" and right-click "My Computer."
Select "Properties" from the menu that appears.
Go to the "Hardware" tab.
Choose "Device Manager."
Click the plus sign next to the Device Manager entry listed "Display Adapters."
Find your graphics card in this list.
Go to the "Drivers" tab and click "Uninstall Drivers."
Click "OK" to confirm the uninstallation process.
Shut your Gateway desktop down.
Pull the power cable out of the back.
Look at the back of the Gateway computer tower for screws on the right side panel or on top of the case for a cover release handle.
