The USB port is typically located near your keyboard and mouse ports on the back of your PC

USB (Universal Serial Bus) ports are designed to allow you to connect over 120 USB devices to the same port.  They use digital technology to keep the signals to each device separate and most USB devices are "plug and play" capable.  The device that you plug into the port will have a cable attached to it with a plug like the one pictured below on its end (although it may be a different color).

Typical USB plug

If you look at the image of the plug closely, you will notice the USB symbol imprinted on it (looks a lot like an Arizona cactus).  You will also see that symbol imprinted near the USB port on the top image.  The plug must be inserted into the port so the symbols face each other.  The symbols are often difficult to see, so try to gently insert the plug and rotate it 180 degrees if it won't go in easily, but don't force it!

Please note that you will almost always need to install the software and drivers for your USB device BEFORE you plug it into your PC, especially if you are not using Windows XP.  Simply insert the CD and follow the on-screen prompts.  Most USB installation utilities will tell you when it is time to plug in your device.  If you plug it in too early, you will probably be instructed to unplug it, so read the directions carefully.  If you don't follow the instructions, your device will probably not function properly, if at all.

Important Points to Remember About USB

• USB is not supported in Windows 3.x or Windows 95, and poorly in Windows 98 1st edition.  Windows 98 Second Edition works pretty well as long as your operating system is stable and has no underlying system problems.  If you are going to use USB devices, I recommend you use Windows 2000 or Windows XP.

• If you have more USB devices than you do ports, simply purchase a USB hub and plug it into your computer's USB port.  Then plug your additional devices into the hub.  This process can be repeated over and over again up to 125 devices.

• If you are using a USB device that incorporates any components such as lights or moving parts (i.e. scanners, printers, etc.) and are USB powered (do not have a separate power cord to be plugged into your household wall outlet), they should be plugged directly into your computer's USB port and not into a hub!

• If your computer does not have any USB ports available, it might still be possible to install them if there are connections for them on your motherboard.  If you decide to purchase the adapter and install it yourself, be aware that connecting it backwards can ruin your motherboard!

• If you purchase USB devices, you should note whether they are designed for USB 1.0 or USB 2.0 since there is a big difference.  USB 2.0 devices will function in a USB 1.0 environment, but they might be slow since USB 2.0 ports (which are standard on all PC's built within the last 18 or so months) are 40 to 50 times faster than USB 1.0 ports.  Some USB devices cannot be used on USB 1.0 ports, so be sure to read the labels carefully before you buy!
