Do not use USB ports on the computer - the way to the top of the problem. Do not work with USB sockets, why does the usb cable do not work

Golovna / Optimization of work

USB - expansion in the mid-90s was the standard for the exchange of data between the outbuildings of those living quarters. This protocol has been developed for connection to the computer periphery and has been sent for replacement to dekilkom earlier ports. Kilkom Approval Standard great companies, including IBM, Intel, Microsoft and NEC. In red 2009 the European Commission adopted roses micro USB as a standard for charging smartphones, which are issued by 14 of the largest cellphones.

USB connector for connecting to a computer Flash-storage devices, hard drives, sound cards, speakers, microphones, MIDI keyboards, Wi-Fi adapters, modems, keyboards, mice, joysticks, webcams, printers, card readers, optical drives and other equipment, as well as for charging batteries and low-power outbuildings. Microsoft introduced the USB support in Windows 98, Apple tried to push the FireWire standard for a century, the pros for a year saw USB take over, and in some products, the Lightning interface, the foundations for USB 2.0 and a number of proprietary protocols.

Officially USB standard 1.x was hardened on the cob in 1996. Vіn transferring data exchange on two speeds: low - up to 1.5 Mb/s and high - up to 12 Mb/s. In 1998, the standard was upgraded to version 1.1, in which case a number of problems with the first version were adopted.

USB 2.0 hardened at the end of 2000 and do the most extensions. Theoretically, the maximum data exchange rate increased to 480 Mb/s, in real life it rarely exceeds 280 Mb/s. The voltage that is supplied through the board becomes 5 with a stream strength of 150 or 500 mA.

A USB cable up to version 2.0 can be used for two wires, two of them are used for data transfer, and two for power supply peripheral building. Ring the screen cable.

The USB 3.0 standard has been approved in 2008, the new data transfer speed is increased to 5 Gb / s, and the stream power is up to 900 mA. The USB 3.0 cable has nine conductors: two for life and one for data transmission. The standard also removed the supplementary specification for the wiki in chargers- The power of the struma becomes 1.5 A, with which the transmission of data is not transferred. As a rule, the contacts for the USB 3.0 port are located on the square in blue color.

In 2013, the USB 3.1 standard was approved, in which the theoretical speed of information transfer grew up to 10 Gb/s. Standard backwards from USB 2.0 and 3.0. The strength of the struma at a pressure of 5 was increased to 2 A, and the power of the struma was also transferred to a force of 5 A at a pressure of 12 and 20 V.

Most outbuildings, which live via USB, support a “hotter” connection that is accessible to shorted ground contacts and, as a result, there is a difference in the potentials of the housings.

Data transfer between a USB host and a peripheral USB device is carried out via a USB controller. Data is transmitted in short power-up packets. Packages go straight forward at once, with which the controller does not check the confirmation of their delivery, which ensures the exchange of money high speed. Packages can be transferred either with a delivery guarantee (for example, at the outbuildings), or without it (when transmitting video and sound).

For connection of attachments to the USB port, a sprat of types of roses was transferred, stinks are controlled by the size, design and design of the contacts. Use as standard roses, as well as proprietary, exchanged products for other companies. Non-standard roses can be used for transferring additional information - for example, at the hour of changing the headset to the phone.

Peripheral attachments, such as a mouse, a keyboard, a webcam, a printer, are connected to the computer via a USB port. It is not uncommon for someone to trap, which sprats of ports cease to work. When connected to a computer, for example, flash drives will not be recognized, the keyboard or the bear may freeze, and the printer may not respond and not change the side.

Іsnuє kіlka other reasons, for some reason, all USB ports on the computer do not work. Let's try to get some power from that z'yasuvati, scho robiti, schob to restore the normal functioning of the computer.

Rechecking the BIOS

First, on what next to turn respect - tse custom BIOS computer. To enter the BIOS, you need a commercial keyboard. If the keyboard is connected to the computer via USB and it doesn't work, you need to connect a keyboard with a PS/2 connector. Otherwise, you simply cannot do anything.

Also, let's go into the BIOS, for which, when starting the computer, it is necessary to press the input key, just sound DEL. Maybe there is another key, as it appears on the screen, it is shown to the helper before the mother's payment. Upgrade to the BIOS, find out the extension, which one is suitable for the integration of attachments (Integrated Peripherals) or the extension "Dodatkovo" (Advanced). Here you should know the subtitle "Onboard Devices Configuration". Itself in the new one knows the parameters that are given for USB robot controllers: USB Function chi USB 2.0 Controller. Numeric parameters are included but enabled (Enabled). If one of them is disabled (Disabled), then point to the new one and press Enter, thereby highlighting it. To make sure the changes are not thrown off, you need to save them by pressing F10, and confirm the savings by pressing the Y or Enter key.

After restarting the computer's computer, we check it out, which works USB ports. І yakscho nі, slid to look for the reason in another place.

USB ports do not work on the front panel of the computer

As an example, you may not be able to use USB only on the front panel. In such a situation, it is necessary to reconsider whether the necessary plugs are connected to the motherboard and not to the wires. For whom do you open a lid system unit And we give respect to the roznіmannya at the bottom of the mother's pay. On the board, write USB1 or USB2, as well as on the well itself. Checked the pads going to the front panel, and if the stench was turned on or in one place it was broken, then you revealed the cause of the malfunction. Poshkodzhenі droti next z'ednati or replace. We will not change the contact at the roses on the motherboard. So varto put respect for the board, stashed on the front panel. Possibly, may be a short hiccup, before speech, such a hiccup may be provoked by a saw, which is stingy. Therefore, it is obov'yazkovo to clean the system unit from the saw.

Problems with the cable itself

Let's start with USB problems, maybe a cable, for the help of some kind of connection, for example, a printer. Qiu injustice is easy to reveal and usunut. Come to the pink flash drive, which is being verified. If it doesn’t work, then we’ll try to connect it to an additional suspicious cable, otherwise we can have it right, for example, a USB hub. Even if the vins are also considered to be practical, the reason is definitely in the cable and yogo next to replace.

Interruptions in eating

There are such situations, if there is simply no life for all outbuildings. For example, when connected zorsky disk, which has two USB sockets, you can turn on the printer or the keyboard. In such a time of tension, the block does not have enough life to provide energy for all the living. If so, the problem may not appear immediately, but after a certain hour after the computer is upgraded. Way out of the situation of the kіlka. If you have installed a low-powered block of life, for example, 300 W, then it would be logical to remember a more powerful one, 450-600 W. You can also use an active USB-hub (from the beginning of life). We allow not only to increase the number of USB devices that are connected, but also to power them from the living unit.

Another reason that comes to the USB robot is the CMOS battery, which is powerful. But if you do, you will, when the computer is turned on, keep the system hour and date that you have beaten. After replacing the batteries, the problem is gone. Alas, not often, then the next thing to do was to overturn other possible mishaps.

Invalid or incorrectly installed USB drivers

Causes related to software problems in Windows 7/10 can be identified with the help of the Device Manager. If you point out that you don’t work specifically on one or the other, the building is outside the port, then you can talk about those that the problem is in the annex itself. Open the Keypad and go to the Attachment Manager. All plug-ins will be installed there. If there are points on the list, if there is a sign of a call to them, or the deputy name should be Nevidomy attachments, then the problem is in the attachment itself. There may be some variants of malfunctions here.

Often USB inputs stop working after reinstalling Windows 7/10. The reason is incorrectly installed drivers, or the necessary drivers may not be found. Have to do it manually and install it manually.

Often, to fix a malfunction, you just need to update the driver. So, it’s alright automatic update Windows, that system itself was installed a long time ago, the actuality of software security is involved, system pardons may appear. Attachment to one’s own starts to work incorrectly, otherwise, to name one’s name ceases to function. To update (reinstall) the USB controller drivers, you can download the CD/DVD with the drivers for the motherboard or get the necessary drivers from the website of the motherboard builder.

Also, with the help of the Outbuildings Manager, you can disable the power saving function for all ports. Open the list quietly, who wins USB accessories, attached to the "USB Controllers", "Misha and Other Vkazivnі Attachments", "Keyboards" branches. Click on the twin bear I will build a necessary, schob v_dkriti vikno authorities. Now go to the tab "Electrical power management" and uncheck the box "Allow the inclusion of this add-on to save power." In such a rank, the attachment will be zadiyany zavzhda and for any furnishing.

If the possession is not known, then there may be a problem with the drivers, so there is a hardware problem that affects the contact, the cable or the malfunction of the controller. Moreover, the situation often happens, if, when an incorrect device is connected, others cease to work normally. The keyboard starts to freeze like a bear, and the printer stops working. The problem is similar to a lack of vitality, so that all tensions go to the wrong attachment, in which case there may be a very short flicker, or another injustice.

USB ports do not work through the controller's code

Just as luck would have it, the success of the USB ports did not help, but the USB controller of the motherboard should be reversed, which should be out of whack. Yakisny repair and diagnostics in such a time service center. As an option to get out of the problem - try installing an expansion board, so the titles are USB PC controller, which is installed at the PCI sockets on the motherboard. Such a solution is cheaper for repairing the USB controller of the motherboard, and if there is no additional USB hub, the problem of missing ports will not be relevant.

Yak bachite, poshuk that usunennya problems with USB-ports to file a bug on the right, and all that, there can be a mass of reasons. The last quest and the exclusion of obviously wrong paths to allow you to reveal that injustice.

As you read this article, it's obvious that you're having trouble transferring USB files to your Android device. Do not boast, you are not the first one, who stumbles before us from similar food.

Fortunately, we know a few ways to solve this problem. So, without further ado, the axis you need to work, so that the transfer of files via USB is re-enabled.

The reason for the pardon of transferring files via USB

There are a few reasons why you cannot transfer files via USB:

USB cable does not support file transfer
Attachment not installed for downloading files via USB
We installed the program Samsung Kies
Micro USB port on your Android device

Krok 1 - Enable file transfer on Android devices

First of all, you are responsible for the mother's ability to transfer files via USB to an Android device.

To enable file transfer via USB, go to Settings > Memory > Press three vertical dots in the right upper codend screen> USB connection to computer> Set ensign order from media device (MTP)

If you think that the problem of transferring files via USB is related to software, try connecting the device to the computer for USB help, select "Camera (PTP)" and clean up again. Help deyakim koristuvachs.

Croc 1.1 - add-on for the "clean" version of Android 6.0 Marshmallow

If you don't see the vague option in the "Memory" section, change your mind that you have increased USB charging. After whom, follow a little trick:

Remove the USB cable from the attachment.
Enable retailer mode. For whom, go to Settings> About phone> click on the number of the pickup number of times, the docks do not show up as a confluence of information that you have become a retailer.
Go to Retailer Settings > Retailer Settings.
Increase the charge via USB.
Block the attachment (block button on the front or top panel).
Connect your smartphone to your computer using an additional USB cable.
Unblock your Android device.
Swipe down to open the help panel and tap "USB Charge".
Select "Transfer Files" from the merging window.
Block the attachment and unblock it again.

vicorist given method, you may be able to transfer files via USB. For some reason, the option is not available without activating the retailer mode.

Krok 2 - View Samsung Kies

Skip this page as you don't have Samsung Kies software installed.

The official Samsung file transfer tool frequently calls the USB file transfer passcode. In order to see Samsung Kies, you need to start the program again, after which select "Visibility".

Krok 3 - Rewire the USB cable

Not all USB cables are the same: they work to transfer files, but they don't. It is recommended to use the USB cable that comes with your Android device. Sound the stink function of transferring files via USB.

If you can't help fixing the problem, try installing AirDroid. Tse software security allow you to transfer files to Android Appliances without USB cable.

With this problem at least once, but the skin sticks: you connect your smartphone or tablet to the computer for an additional USB cable, but, charging cream, nothing happens. The computer does not bachel the phone, otherwise it will signify it as an unknown attachment. The situation is expanded, but ambiguous, and the reasons, for which they are blamed, are rich. Today we are choosing to identify such problems and how to deal with them.

Before the situation, if the PC does not recognize connections to a new mobile device, induce software and hardware failures:

I will add the driver to the operating system of the PC.
Uncertainty of the model driver I will add.
Vіdsutnіst vіdsutnіst vіdsіtnіstі usb driver іr zbіy і robotі.
Connected by cable, unsuitable for data transfer, or poshkodzhenim.
Incorrect USB socket (both on a computer and on a telephone), socket group or USB controller on a PC.
Incorrectness caused by the possession of a computer, blocking by static electricity.
Pardon in the system nalashtuvannyah phone.
Blocking access to the phone with programs that work on a computer (including those with a virus-infected gadget).
Zbіy at the robotі program, for the help of which the synchronization of the phone and the PC is fixed (like a win).

In times software problems the computer, as a rule, does not display in the memory of the phone, but the device, when connected to a new one, is normally charged. As the problem is blamed due to physical inadequacy, charging is most often the same, but there are blames, if there are less transmission lines.

christen the colo possible reasons help to analyze the previous situation - what happened before him, like a problem. For example:

We have rearranged operating system on the computer, or they saw a part of the drivers (the reason for the required driver).
The phone (tablet) stopped showing after the firmware, virus cleaning, remote programs, optimization and other manipulations with the OS (down with the robot's operating system of the mobile device).
If you recognize a mechanical inflow (USB socket is plugged in) or if you go to the repair shop (after replacing the parts, you need a driver of a different version, or the error will not be fixed again).
You have to use a USB-cable, as you have never connected your phone to a computer before (appointment cable only for charging or zipping) and so on.

Shvidko vinuvattsya problems

The prosthesis of the causal connection significantly eases the localization of the problem, but about half of it does not change anything in particular. As it is with you yourself, the steps can help you to find out, de vinikli zbіy - for your mobile device, PC or USB-cables.

Rotate the cable in the area of roses (in these areas, it is often broken) and be careful not to show the phone (tablet) at the conductor or the dispatcher of the computer. Abo connect the add-on with another, behind the worker and accessory cable for data transmission.
Connect the phone to another computer, as well as another mobile device to another computer. If the phone does not show up anywhere, then the problem is definitely in the new one. Those same at vipadku with a computer.
Probably the reason is in the computer, flipping the phone on all USB sockets, perhaps the problem is in one or more of them (for example, less than the front group).

If you came to the visnovka, that there were problems with the cable, just replace yoga. How to work in other situations, read on.

Blame the trouble - phone. What work?

If the diagnostics clearly indicates a problem with the mobile device, hover down in order. After the skin crack, check that the inaccuracy is fixed. Yakshcho nі, go to the offensive.

Reboot the device.
Connect phone to computer. After the day, push down the menu curtain shvidkikh nalashtuvan And change your mind that the list "Pidklyuchiti yak" does not have "only charging", and also "camera" or "media attachments". Select the USB storage option.

Open the system android customization(In older versions - "Parameters"). Go to the branch "Bezdrotovі merezhi". Activate the modem mode. Abo navpaki, yakscho vіn uvіmkneniy - vymknіt. In some editions of Android, this parameter is controlled not only by the modem, but also by connecting the gadget to the computer as a storage device.

Experiment with setting the plug-in to USB enabled mode. For the distribution "System" and "For retailers", enter the parameters. Change or set the ensign for the "USB Enforcement" item.

Look at the phone as a computer, remove it and remove the battery from the new (phone) battery (for sure, it’s out of place). After 5 minutes, install the battery on the plate, turn on the device and repeat the test.
To see the programs, after any of them appearing zbіy. If the connection does not work in a specific synchronization program, clear the cache. If it doesn't help - reinstall (and on a mobile device, and on a PC) or try a substitute analog.
Scan the accessory with an antivirus.
I’ll add the discounted operating system to the factory settings.

Blame the trouble - the computer. What work?

Shut down the OS, unplug the PC from the socket (or press the key on the life block) and press the Power button for 15-20 seconds. It is necessary to discharge the capacity and znime of a static charge, which can block the connected attachment.
If the phone is not recognizable by more than one group of USB ports, open the cover of the system unit and change the connection. Until the speech, it’s normal to charge the mobile attachment through the port, but don’t talk about the correctness of the other.
Take over the operating system. Open the extension manager and turn it over, which is in the list of portable extensions, and in the middle is your phone. For example, the present wine, but for the meanings with a black arrow near the number (unmarked), click in order with the right button of the bear and select the command “Switch off attachments” from the menu.

As in the list of possessions, there are no annexes (marked with a hail sign in the yellow tricutnik), perhaps one of them is a telephone. If you need to change the connection, what is the fault, open a mobile device with USB. If there is no nevidomy attached to the list, then so it is. The first reason for the failure is the presence of a required driver in the system. How to reset and download the driver to your phone, just a little bit lower.
The problem with recognizing the connection of the attachments can be through a zbіy zavantazhennya, poshkodzhennya or the presence of USB drivers. In what direction hail signs will be at the "USB Controllers" branch.
Did reinstalling the drivers help? Scan your computer's disks with an antivirus and turn on your programs at the same time. To the point, the rest can block access to the mobile device like to wear it, like on a new one it is suspected or obviously shkidlivy software. Otzhe, on the virus varto check and phone tezh.

View the programs after any failure, or restore the system to a checkpoint created on the day, if there was no problem yet.
As for the phone, the computer does not recognize other attachments, connects via USB - mouse, keyboard, printer, flash drives, etc. (the stench is charged at any time - it’s not ostentatious) but whatever. then from the periphery. It is possible to determine guilt in domestic minds by the method of handwriting inclusion, or replace possession with a reference.

How to install a mobile device driver and USB on a computer with Windows

iPhone

Connect iPhone to PC.
Open the folder %CommonProgramW6432%\Apple\Mobile Device Support\Drivers (to avoid typing the command manually, copy the stars, paste into address row be it a folder and click the transition button). It has 2 files (chotiriox) with .inf extensions - usbaapl.inf and usbaapl64.inf.

Vіdkryte context menu skin s zikh files and select the command "Install".
After installation, restart your computer.

Android

Smartphones and tablets under Android, such as Samsung, Xiaomi, Lenovo, Meizu, HTC, etc., as a rule, do not create enough folders to save their drivers, and on official sites they often do not know, just download and reinstall . To that for the cob varto doviriti reinstallation already present in the Windows driver system.

Yak tse robiti:

Open the context menu of the problem device at the dispatcher of the extension. Select the "Update driver" option.

At the next start, select an automatic search for an update. If Windows doesn't know anything about it, indicate another point - manually installing that search for drivers.

Then press "Select from the list available on the computer". The new window has all the drivers mobile outbuildings already installed on the PC.

To sound a search, in the "Choose a driver for which I will build" section, put the "Tilki sumisny" sign. Select those that are more relevant to your request (for example, the list has more than one item) and press "Dal" to go to the installation.

Having correctly loaded the driver, restart the computer.

As if reinstalling the driver, while already standing at the system, did not help, it happened to search more in the open spaces of the merezhі (with a risk of zavantazhit zamіst shukanogo vіrus), so download them only from the above and distorted sites, on 4pda.ru, and before installing, change them. .

Drivers for the most popular models of mobile gadgets are also available from the "USB Drivers for Android" add-on, which is available for free download on Google Play.

USB drivers for Windows can be easily found on the websites of laptops or laptops. motherboards desktop PC. Sometimes they enter the warehouse of the driver for the chipset.

How the phone is not recognized in firmware mode

For those that the computer and the phone do not boot one by one in the fastboot mode, it indicates the Waiting for device notification, as it appears in the firmware program. The most common pardon is blamed on the driver system for a mobile device, then we will kill those that are written above - reinstall the driver or download and install it again.

Yakscho did not help:

Change, you will accurately follow the instructions for the work with the firmware installation program and it will be launched under the name of the administrator.
Turn over, chi on the smartphone is loaded via USB (yes, it’s not, uwmknіt), and the device itself is in the bootloader mode. If this mode is blocked, find the instructions in the next section on how to unlock the lock for the model itself.
Connect the phone with the shortest possible cable and the right cable to the rear USB jack, without breaking any other adapters and hubs.
Perhaps your phone does not support the USB 3 standard (blue jack), so please connect it to USB 2.0 (black jack).
Install all Windows updates on your computer.

If you need to fix the problem next time, try to fix the firmware on another PC. In short - with a different version of the operating system.

If the problem is with the broken physical interface

Incorrect physical interfaces, especially on mobile gadget, but not vikoristovuvati zovsіm (do not navantazhuvati strum, schob zapobіgti polomtsі), navіt like a phone or a tablet save building before charging through them. You can organize the transfer of content either for dartless sting(Wi-Fi, bluetooth), or via bad services, which are available on that other extension. Zokrema, iTunes and iCloud for Apple technology, Google Drive, Yandex Disk, Dropbox, Microsoft OneDrive and many others - for everyone.

Useful services to manually speed up for transferring photos, videos, music, documents and other types of files. There are enough opportunities to synchronize contacts on Android and PC Send Gmail. And if you want to use your phone directly from the computer, you can put an add-on on them for MyPhoneExplorer (comprised of 2 parts - for the phone and for the PC), which supports and dart, and bezdrotove z'ednannya attachments without requiring the installation of drivers. It's too manual.

In a word, you leave it forever and often richly simple, you don’t give up at first glance.
