Help Using USB Cords
USB connections have changed the way we operate technology. Universal Serial Bus was introduced in 1995 by Intel, Compaq and Microsoft as well as several other smaller computer companies. USB cords help transfer information from a host device, usually a computer, to a peripheral device through ports. You can now connect many different devices with a USB cord. Some of these devices include cameras, keyboards, printers, scanners, webcams and MP3 players. Increasing your knowledge of USB cords will improve your use of them with your devices.

Combinations
-
USB cords come in a number of combinations as far as their end connectors are concerned. An A-style connector has a flat, rectangular end. The A connector is used primarily on host controllers such as your computer. The B-style connector is usually the end that's used on peripheral devices such as scanners, keyboards or printers. It's square with slightly beveled corners. Most devices that use a USB cord require an A-B cable -- one with an A-style connector on one end and a B-style connector on the other end. Mini and Micro-USB A and B connectors are seen frequently with cellphones, digital cameras and GPS units. These types still support a high speed for transferring information but have smaller B ends.
Restrictions
-
One of the major restrictions with a USB cord is the length. To clearly transfer information, keep the length of a USB cord for a high speed connection under 16 feet 5 inches. Keep the length between low speed devices to less than 9 feet 10 inches. Full speed devices include scanners and digital cameras. Low speed devices include keyboards, mice and joysticks. You can add a USB hub to increase the distance between devices by about 16 feet. Check the user guide for each individual device to determine the maximum length you can use for a USB cord.

Uses
-
You can complete many tasks by connecting your device to your computer with a USB cord. Besides attaching computer hardware such as printers, keyboards, webcams or scanners, you can transfer information and other media to your computer. Hook up your digital camera to your computer with a USB cord and you can upload pictures to your computer, edit them and send them to a local store for printing. You can connect your MP3 player to the computer and download songs from the Internet. You can also connect other USB devices, such as e-readers, to your computer to charge.
Requirements
-
Any new computer supports USB and probably comes with multiple ports for connection. If your computer was made sometime in 1997 or later, it probably supports USB. Free USB evaluation programs are available on the Internet if you're unsure of your computer's USB compatibility. If a USB device needs additional software to work with your computer, it normally comes with a CD or you can download additional drivers from the manufacturer's website. As long as your operating system supports USB, you can plug in the device and the USB host controller should automatically detect it and get it ready to use.
