How to Choose an USB Extension Cable?
- If you want to connect a piece of hardware to your computer you most often use a USB cable. However, if the device is out of reach with the provided USB cable you need to obtain an extension cable. There are a few factors that can have an impact on your USB extension cable, including the length you need, the type of USB cable and what kind of USB adapter end you need to use.
Instructions:
- Things You'll Need: USB extension cable, Tape measure
- Measure the distance between the computer and the hardware you want to connect. This helps to determine the length of the USB extension cable you will need to purchase
- Decide whether you want to connect the extension cable directly to the ports on the hardware and the computer, or if you want to plug it into the cable provided with the hardware. This will determine the type of connectors you need on the extension cable
- Look at the actual USB ports on the computer and the hardware, or the free end of the USB cable you will use with the extension. There are A-type and B-type USB cables. The one most otten used is the A USB cable. The port on this cable is rectangular and is about 1/2-inch wide. Type B resembles a square connector and is roughly 1/3-inch inch thick. Identify the ends of your existing USB ports to make sure you pick out the correct extension cable
- Find an extension cable that has a male connector on each end. The male connector is inserted into the USB port. You need this kind of extension cable to connect it directly to the computer and hardware
- Look for an extension cable that has one female end and one male end. This is if you plan to use the cable already provided, plus the extension cable. The provided cable plugs into the USB port of the hardware and the other end of the cable plugs into the female end of the extension cable. You then plug the male end of the extension cable into the USB port on the computer

- What are typical transmission speeds for USB cables?
Generally speaking, USB cables are classified into one of two different bandwidth groups: 1.1, which transfers data at a maximum rate of 1.5 Mbit per second, and 2.0, with a 480 Mbit per second data transfer rate. USB 2.0 is backward compatible with the lower data transmission requirements of 1.1, but the substitution can't be reversed; 1.1 just can't deliver the rate of data transfer that USB 2.0-rated devices need.
In addition to the bandwidth classifications listed above, USB devices can also be labeled in the following "speed" categories, which specify the amount of bandwidth they need to operate:
Low Speed: The " low speed" rating indicates that a device requires minimal bandwidth (1.5 Mbit/s) to function, so it can be used in conjunction with either 1.1 or 2.0 USB cables. Joysticks, keyboards and computer mice are a few common examples of low speed devices.
Full Speed: Devices labeled "full speed" need a signal rate of 12 Mbit per second. Since this is such a common bandwidth requirement, all USB hubs on the market have been designed to support Full Speed. And even though the data transfer speed is higher, Full Speed - like Low Speed - transmits equally well via 1.1 or 2.0 USB cables.
High Speed: " High speed" USB devices run at 480 Mbit per second, and require a 2.0-rated USB cable.
- What does it mean when USB cables and devices are described as “hot swappable?”
One of the most convenient features of USB cables and devices is their ability to be "hot swapped," which means that they can be plugged into - and unplugged from - a computer as needed, without that computer needing to be powered down first.
- How do I know I plug in a Hi-Speed USB device?
The simplest way is to look for a certified Hi-Speed USB logo on the retail packaging or on the product itself. The logo is exactly as shown on the right; it tells you what you are plugging into your USB port has passed the Hi-Speed compliance tests, meaning the product can enter Hi-speed USB mode if your system supports it.
