 Your computer may have USB ports About USB devices and Mac notebook computersIf you have a Mac notebook computer, USB devices can cause your computer’s battery to become depleted faster. If you plan to use the device for an extended period, it’s a good idea to connect the computer’s power adapter. About disconnecting USB storage devicesBefore you unplug a USB storage device while your computer is on, eject the device by dragging it to the Trash. About connecting multiple devicesYou can connect more than one device to a USB port Be sure to connect USB 3.0 SuperSpeed devices to a USB 3.0 SuperSpeed HUB, USB 2.0 Hi-Speed devices to a USB 2.0 Hi-Speed hub, and so on.

If the computer has fewer USB ports than the number of contenders for it, "office acrobatics" begins - alternately switching each device. The occupation, of course, is not the most pleasant one. Fortunately, we live in the age of information technology, so this problem can be solved with a simple USB hub. InstructionsStep 1Choosing a USB hub. You can buy it at any computer store or subway stall. We recommend paying attention to gift shops - there you can choose an inexpensive hub with a colorful design (for example, in the form of a mouse or a green android robot) instead of a dull heap of wires. If the hub needs to be on a table, and the computer is somewhere far below, the standard cable length of the USB hub may not be enough. In this case, buy a USB extension cable, its price is usually around 100-200 rubles. Step 2Connect the USB hub to one of the USB ports on your computer. If the wire is too short, use a USB extension cable. Step 3It is better to connect the keyboard and mouse directly to the computer, and the rest of the devices to the hub. Otherwise, you may experience slight delays in the operation of multiple devices (for example, keyboards, mice, and webcams). Just about every peripheral made now comes in a USB version. Here's a list of some of the USB devices that you can buy today:
Most computers that you buy today come with only one or two USB sockets. With so many USB devices on the market today, you easily run out of sockets very quickly. For example, on the computer that I am typing on right now, I have a USB printer, a USB scanner, a USB Webcam and a USB network connection. My computer has only one USB connector on it, so the obvious question is, "How do you hook up all the devices?" The easy solution to the problem is to buy an inexpensive USB hub. The USB standard supports up to 127 devices, and USB hubs are a part of the standard. A hub typically has four new ports, but may have many more. You plug the hub into your computer, and then plug your devices (or other hubs) into the hub. By chaining hubs together, you can build up dozens of available USB ports on a single computer. Hubs can be powered or unpowered. As you learn in How USB Ports Work, the USB standard allows for devices to draw their power from their USB connection (all USB cables contain two wires -- for +5 volts and ground). A high-power device like a printer or scanner will have its own power supply, but low-power devices like mice and digital cameras get their power from the bus. The power (up to 500 milliamps at 5 volts) comes from the computer. If you have lots of self-powered devices (like printers and scanners), then your hub does not need to be powered -- none of the devices connecting to the hub need additional power, so the computer can handle it. If you have lots of unpowered devices like mice and cameras, you probably need a powered hub. The hub has its own transformer, and it supplies power to the devices that connect to the hub so the devices do not overload the computer's power supply. The Universal Serial Bus can easily handle both a scanner and a printer, even if you are scanning and printing at the same time. The original USB supports up to 12 megabits per second, and USB 2.0 supports up to 480 megabits per second -- considering that most devices consume only 6 megabits per second, you can definitely run more than one device at a time.

It is the most popular type of port used in computers to connect them to external devices such as keyboards, mice, printers, phones, cameras and more. It is common for personal computers to have at least two USB ports. What is the difference between USB and USB-C?The main difference between a USB and USB-C connection is that it the latter can charge devices at a faster rate. Most USB-C ports can deliver up to 100 watts of power. Why did my USB ports stop working?Common reasons for USB ports to stop working include hardware failure and problems with software incompatibility. Your PC may require updates or the operating system may be missing important pieces of software. In some cases, your USB port may actually be physically damaged. What is a USB port extender?A USB port extender is a device that increases the distance at which you can connect a peripheral to a USB port and increases the number of ports available. Most USB extenders draw a lot of power, and thus, drain your laptop battery very quickly. How many devices can one USB port support?A USB host can support up to 127 devices in a "tiered star" formation, but you can run out of bandwidth if you use too many of them at once.
Can you split a USB port into two?Can a USB port be split? Yes, USB ports can be split, with an upper limit of 127 USB ports on a single PC. When you split a USB port you are reducing the power available to all USB ports on the machine.
Can multiple USB devices be connected to a computer?The USB specification supports up to 127 devices, which means you could theoretically connect up to 127 different USB devices up to your computer. If you needed more than 127 devices, you could even install another USB card to connect additional USB devices to the computer.
Can a USB port be shared?USB over Network allows to use remote USB devices shared over a local network or the Internet. It does not matter if you are located in another office or even country, now you can use any USB device remotely as if it was attached to your computer locally.
