How to add USB ports to your computer. How to speed up a USB port, what reasons are hidden behind the low speed of their operation


This is the most commonly used interface in a computer. WITH via USB connect almost all peripheral devices, flash drives, modems and other equipment. Therefore, it is not uncommon in the process of using a computer to find that the available USB port ov is not enough. In such a situation, users have a completely natural question of how to increase the number of USB ports. From this material you will learn how to quickly and without serious costs solve the problem of a lack of USB ports.

Increasing the number of USB ports using a hub

The easiest option is to purchase a USB hub. A USB hub is a device that allows you to connect more than one USB device to one USB port. Thanks to the features of the USB interface, devices connected to a computer using such hubs work as if they were connected directly to the computer.

The only problem with using hubs is connecting devices that require serious power via USB. For example, external hard USB-powered drives, when connected to a computer via a hub, can work very slowly or are unstable. To avoid such inconveniences, it is better to buy USB hubs With additional food from the socket.

It should be noted that when selecting USB hub, you shouldn’t save money and buy the best cheap model. Otherwise, there is a high risk of simply losing money. Cheap USB Hubs not only fail quickly, they can damage the devices connected to them, which can result in significant replacement or repair costs.

Increasing the number of USB ports using a controller

The second option that can help increase the number of USB ports is to use an additional controller. Such controllers are made in the form of a separate board and are connected to PCI or . For installation additional USB controllers you will have to open the cover system unit, but you will get more stable and reliable operation compared to USB hubs.

Typically, controllers that connect to PCI interface, provide the user with 2 or 5 additional USB 2.0 ports. And controllers using PCI Express x1, provide up to 2 additional USB 3.0 ports.

So, if you decide to increase the number of USB ports, then you need to find out if there are free connectors for connecting a cable with USB ports. If these connectors are found, then everything is simple. You need to purchase a cable with ports. Such a device is inserted into the front panel of the computer case and connected to the connector on the motherboard (see figure). See the motherboard manual for the exact location of the connectors. There are also options for outputting ports to back panel housings. Cost from 5$

Step 2

If you don’t have free connectors, or you don’t want to bother with connecting them, then an external USB controller will help you. This device is a board that contains several USB ports, as well as a host controller. These devices come in two types. The first is inserted into the PCI slot on the motherboard, and the ports are output to the rear panel. The second type is inserted into the front of the case and the ports are output to the front panel of the PC. Similar devices cost from $20.

Step 3

Another option involves using USB hubs. A hub is a device with multiple USB ports that connects to a free USB port. Speaking in simple language, A USB hub is an extension cord with a splitter. This method is the fastest and safest, because no need to go inside the computer. Such devices cost from 25$.

I haven't stopped describing yet USB operation ports. This time I want to touch on the topic of USB speed. All modern laptops and desktop computers equipped with USB interfaces. You can increase the number of connected devices to several dozen using so-called hubs. There are also devices that do not care about USB speed, for example, mice and keyboards, but memory storage devices (flash drives and hard disks) are very dependent on these parameters. It happens that when transferring files to a disk connected via USB, it is very small, and this is not good.

What to do if the USB port is slow? If such a situation arises, I have prepared a number of reasons that describe these problems, as well as solutions that will help speed up USB performance. I hope this article helps you.

Reason #1 – old USB types

This means that your device has ports that belong to the old specification. Now there are three types of ports: USB 1.0, USB 2.0, USB 3.0, there are also USB version 3.1.

There are, of course, many differences between these versions, but mostly not related to appearance, but in terms of speed.

Of course, USB 3.0 is the fastest; it is also marked in blue, so it will be difficult to confuse it with other versions. I also want to remind you that if you have a device, let's say HDD, which is capable of working on USB speed 3.0, but you connected it to port 2.0, then it will not work with maximum capabilities.

Here are a couple of parameters for each port:

USB 1.0

  • Maximum speed 12 Mbit/s;
  • Cable length Max 5 meters;
  • Number of connected devices Max – 127;
  • Supply voltage – 5 V.

USB 2.0

The standard has undergone significant changes, which you can find below.

  • Maximum data transfer rate 480 Mbit/s;
  • For keyboards, mice and joysticks, 1.5 Mbit/s is sufficient;
  • For audio and video devices – up to 12 Mbit/s.

USB 3.0

IN this standard you can notice the increase in data transfer rates up to 5 Gbit/s, and with the emergence of version 3.1 up to 10 Gbit/s. It also became possible to simultaneously transmit and receive data, which increased the speed of work. It has a high current strength, which helps to easily connect any hard drives, as well as charge some devices, such as smartphones, faster. USB 3.0 is compatible with all previous standards.

What should be done? I advise you to buy PCI controller, but more on that below.

What ports are on your laptop or computer?

I have already written about this in more detail. But there are a couple of points that are not included in that article. Firstly, you can use the documentation for your motherboard or laptop and technical specifications find out everything.

The second point is to use special programs, which show all technical and software characteristics computer.

As an example, I will give the utility AIDA64, since I often use it myself. You can download and trial version from the official website. So, let's go to the section "Devices" and there we select the item "USB Devices", on the right you will see all the ports that are built into your computer.


Reason #2 – maximum speed is disabled in BIOS

Sometimes it happens. If you notice that the speed of that USB 2.0 is suspiciously low, then look for USB-related settings there. They can be located in the tab Advanced. There you can switch the parameter to Hi-Speed or FullSpeed. I can’t tell you exactly, because different versions BIOS parameters labeled differently.

Reason #3 – No USB ports

IN modern laptops and motherboards this is almost impossible. At least a couple of USB 2.0 ports will definitely be built-in. Of course, if your situation is completely different, then you can purchase a controller without any problems PCI USB, for example, versions 2.0 or 3.0, or all together. For the price they are not very expensive. For example, you can find a USB 3.0 controller for 700 rubles.


Installation is also quite simple. The main thing is to know what a PCI slot looks like. Before taking any action, be sure to turn off your PC and unplug it. Next, you can pull out the cover of the system unit and check the free PCI slots; if there are any, then insert our controller there. After turning on the computer, everything will already work, the necessary software will be installed automatically.



Reason #4 – operating speed at USB 1.0 level

Another problem arises. In this case, you may even see a message like this: “A USB device may work faster...”. This means that you have a free high-speed port on your PC, and you need to connect devices to it.

If you notice that USB 2.0 or 3.0 has a speed of 1.0, then the culprit may be. Maybe they need to be updated to the latest versions, or deleted, and the system will install them again. This is done as follows:

  1. Go to device manager - keys Win+X and selecting the appropriate item;
  2. Open the tab "USB Controllers";
  3. On desired device double click and then go to the tab "Driver", where we click "Delete".
  4. Click on the tab "Action", and then select the item "Update hardware configuration".


There is also one caveat when copying files. The speed will be much slower if you copy many smaller files. If you want to higher speed, then collect such files into one archive.

Instructions

Find out your motherboard model and read its review on the Internet. Please note that increasing the voltage distributed to the computer's USB ports is only possible in latest models motherboards and only if in the BIOS this parameter set below maximum.

Never increase USB voltage using non-standard tools or overclocking - you will simply ruin south bridge motherboard or, even worse, the power supply or the entire computer.

Open the BIOS settings and view the voltage distribution settings for the USB ports. If this option is possible, increase this parameter to the maximum possible and exit, saving the changes. If your mother card does not support such a function, you can replace it with more new model, depending on how much you need it.

To increase the power supplied to the USB ports, use special autonomous units 5V supplies, which are sold in computer stores in your city. For each USB port in your computer, a certain number of power units (500 mA) are allocated, and you cannot change this indicator, just as you cannot increase the USB voltage higher than possible - you will simply damage the motherboard chips.

Use special adapters to connect USB devices, this will help you keep the ports on your computer in good condition longer. However, please note that for the ports to operate at full capacity power These adapters and the cables you use must be of appropriate quality, since various Chinese cords and non-original cables to connect portable devices damage ports and reduce data exchange speed.

Helpful advice

Use original cables to connect devices.

Usually personal enhancement computer achieved by replacing some important devices. Sometimes it makes sense to simply add new equipment that can work in conjunction with existing analogues.

You will need

  • - AIDA;
  • - instructions for the computer.

Instructions

Overall computer performance is calculated from four main devices: central processor, random access memory, video cards and hard drive. It is important to understand that replacing one of them will not guarantee a significant increase in PC power. First, find out the characteristics motherboard And specified devices.

Install the AIDA (Everest) program. Launch it. Study the parameters of the devices described in the previous step. Find out the number of cores in the central processor and their operating frequency. Check the total capacity of RAM modules.

When studying the characteristics of a video adapter, take into account not only the amount of memory of this device, but also the size of the data bus bandwidth. In case of hard drive pay attention to its size, and to the speed of data processing.

Select the equipment that needs to be replaced. Be guided by your own needs. If you want to achieve quick launch large quantity applications, discard the idea of ​​​​improving the video card. Focus on memory modules and processor.

If you're concerned about slow processing times, consider replacing your hard drive. Review the motherboard specifications to determine the types of devices that the hardware supports.

When choosing a CPU, pay attention to the socket type. To replace RAM, it is important to know the type of slots used in your computer.

If you decide to replace the hard drive, check available interfaces for connecting hard drives. The most commonly used connectors are SATA and IDE. Please be aware that installing new hardware may require replacing the power supply.

For a long time now, quite a beard-covered instruction has been floating around the Internet on how to determine the gender of your computer. To determine whether your computer is a man or a woman, open Notepad and copy there without external quotes next text: "CreateObject("SAPI.SpVoice").Speak"I love you"".

Helpful advice

In order to find out what gender your computer is, you need to do a very simple operation: 1) Open notepad. 2) Copy this phrase into it - CreateObject("SAPI.SpVoice").Speak"I love you". In general, GetVoices returns the voice preinstalled in the system. Using the search, you can sort through the voices and choose the one you like if the existing computer floor does not suit you.

Sometimes your computer doesn't have enough free USB ports. To connect all your existing devices at the same time, their number needs to be increased. There are three ways to do this.

Instructions

The first method requires turning off the power to the computer. Buy special brackets with USB connectors. Install them on the back wall of the system unit instead of expansion cards. Locate the connectors on the machine's motherboard for additional USB ports. Find the pinout of these connectors in the instructions. Make sure that it is the same as on the mating parts at the ends of the strip loops. If necessary, rearrange the contacts in the mating parts. Attach the brackets to the motherboard. After turning on the computer, be sure to check the correct connections on all additional ports so as not to damage the expensive equipment connected to them. For such a check, you can use any low-value device, say, an unnecessary one with a large number of damaged cells.

To add ports using the second method, which also involves turning off the computer, purchase a special USB adapter designed for installation in a PCI slot. If the number of slots and the power of the power supply allow, you can even buy several of them. Each of them has from two to four ports. Install them in free PCI slots. This way you can even add USB 2.0 functionality to older motherboards that have USB interfaces 1.1.

The third method is to use a USB hub. They come without external power and with it. Use the first ones if all the loads are low-power. Use the latter, for example, in conjunction with removable hard drives. USB hubs can be connected and, and models with can be used to secure motherboard computer (especially) from failure due to power overload. Never connect devices to a hub with external power until it has been supplied with it.

On standard motherboards the maximum voltage for USB ports – 5 volts. This setting cannot be changed in big side without causing harm to your equipment, so the only solution is to purchase a new motherboard to replace the old one, after making sure that voltage its USB ports have more.

You will need

  • - screwdriver.

Instructions

Find out your hardware configuration. To do this, open the properties of your computer in the Start menu and in the window that appears with several tabs, go to the one that is responsible for setting up your hardware. At the top right corner, find the device manager launch button, click on it and in the list of equipment that appears, copy the name of the motherboard, processor, and so on. Many laptops also include motherboard model information on a sticker on the back cover case next to the markings of the computer itself.

Find out which models of motherboards match the configuration of your equipment, and choose among them those with more power for USB ports, preferably up to 12 volts, this is the maximum for modern motherboards.

Make sure to purchase such equipment, since in most cases standard voltage is sufficient for charging purposes. Also note that an outdated hardware configuration may not be suitable for installing a new motherboard model.

Install the new motherboard into your computer, connect the power cables and necessary cables, best of all, if you are not sure, trust this matter knowledgeable people or employees service centers. Be careful, many Internet portals contain information on how you can programmatically increase voltage USB, some of the methods described there work, but in most cases their use ends in damage to the motherboard and more.

If you want to increase voltage USB for any devices, use the original cables that are included in the kit or purchased from the manufacturer, since when using others, the result of using the voltage is not fully guaranteed.

How often has a situation arisen in our lives when the ports on a laptop are sorely lacking, or the ports we need are missing altogether. However, few people know that this situation, in most cases, is easily fixable.
There are several ways to increase the number of USB ports and add missing useful interfaces to your laptop. Below we will talk about the most accessible of them.

To increase the quantity USB connectors you can use USB-Hub

The essence of the device is to make several USB ports out of one. Using a USB-Hub, which, when connected, will take up only one USB port, we will get from 2 to 16 ports. The hub connects normally USB cord, included in the kit, and takes power from the USB port on the laptop.

However, for correct operation equipment with high power consumption ( external HDD, phone charging from a USB connector) You may need a hub with an additional, external power supply.

Using USB-Hub, you will save yourself from situations when you have to pull out a flash drive or mouse to connect them instead external hard disk or phone for charging.

On older laptop models, you can use expansion cards for the PCMCIA slot.

Unlike USB-Hub, with these cards you can not only increase the number of USB ports, but also add interfaces and devices missing from the factory without purchasing new laptop. The PCMCIA connector is located inside the laptop case and is usually closed with plastic “curtains” or a rectangular-shaped plug.

Nearby there is a button that helps you remove the plug or card from the slot. The card is inserted into the slot and protrudes slightly from the laptop body.


PCMCIA cards come with different interfaces. Here is a list of the most popular ones:


PCMCIA on LAN (RJ-45 connector)

PCMCIA to COM (RS-232 connector)

PCMCIA to LPT (printer connector)

PCMCIA on 1394 (firewire)

…and others

For modern laptops, expansion cards are used for the EXPRESSCARD slot.

The slot cover is also rectangular in shape, but narrower than that of PCMCIA. Or the same width, but one of its corners has a cutout.

Their difference from PCMCIA is the form, a more expanded range of ports and devices, as well as more high speed data transmission.
The main advantage of EXPRESCARD is its support for more modern ports and devices. Here is a small list of the most popular:

EXPRESSCARD on USB ports version 2.0 and version 3.0

EXPRESSCARD on Wi-Fi and Bluetooth





EXPRESSCARD to COM (RS-232 connector)

EXPRESSCARD SSD drives and flash drives



EXPRESSCARD sound cards

EXPRESSCARD modems and cards for SIM



… and others

ATTENTION! PCMCIA and EXPRESSCARD ports and devices for them are physically incompatible!
