Why a computer or laptop does not see a USB flash drive and a removable hard drive. Why does a computer or laptop not see a USB flash drive and a removable hard drive Usb 2.0 does not work but 3.0

Not so long ago, I encountered such a problem on an already installed Windows 8.1 operating system. The computer was handed to me in order for me to reinstall the system from Windows 8.1 to Windows 7, and first of all I checked the USB input. Plugged in a flash drive computer mouse, but the laptop did not see any equipment. Then I noticed that the USB port itself is blue, and this indicates that it is USB 3.0

It does not work for only one reason, the drivers for USB 3.0 are not installed in the system

To check for the presence of drivers in the system, let's look in the device manager for question marks and other signs next to installed drivers. If there are no suspicious signs, then the driver is installed in the system, but it is either old or does not fit the operating system.

What are the options for solving the problem?

1. Alternatively, I uploaded USB 3.0 drivers for Intel, AMD and Asus motherboards to my server. You need to download one of the presented drivers.

How to find out what motherboard you have?

Laptops usually have a sticker like INTEL or AMD.

In Device Manager, under USB Controllers, look for the following:


As you can see in the photo above, I have a motherboard installed with Intel chipset, respectively, the driver needs to be downloaded from this particular manufacturer.

2. Download the program Driver Pack Solution, then install or update the USB 3.0 driver. The program is completely free and does not require installation, but this1 version requires an internet connection.

3. If the top two options did not help you, you must either install from the disks that were given when you bought the computer, or use my article "Where to download drivers". In this article, I showed how to download firewood from the official websites of manufacturers such as Acer, Samsung, Toshiba and Dell. The video is attached to the article.

But I think that the first option will definitely help in solving this problem.

qvad, thank you for the tip. Only I don’t understand what this program for flashing a flash drive did? Wrote that it was Low Level Format ( Low level formatting). Please explain what happens with low-level formatting?
As I understand it, all cells of the microcircuit are checked by flash memory, and when broken cells are found, they are somehow blocked by entering the numbers of these broken cells into the controller's EPPROM memory firmware? Am I thinking right, or am I just dumb on the contrary? Thank you!

Question: Bios does not see a flash drive via USB 3.0


Motherboard MSI 880GMA-E45 (MS-7623). The BIOS version is the latest on the manufacturer's website. Tell me what's wrong? From under the operating system, the flash drive works fine. determined...Flash Transcend 16GB

Answer: not to create new theme I will write here.
Motherboard ASUS M5A78L-M LX3. USB 3.0 does not support. But what does it matter, anyway, a flash drive that supports USB 3.0 should work correctly, right?
On the flash drive, the installation of Windows 8.1, and it is bootable (exFAT), has already been checked and used on other computers (though more modern, laptops).
But when I selected it in the F8 window, only the cursor flickered on dark screen.

Update: everything is ok, this computer just didn't understand exFAT.

Question: The connector for the fan does not work


Such a mother
I took it used, the owner did not mention this, and when I discovered it (a month later) it was too late, and I lost his contacts.
In general, one fan connector does not work. CPU_FAN is fine, it works, the second one does not want to, I tried different coolers. What is the problem, what is it necessary to solder? I don’t want to take it in for repairs for the sake of such a trifle, can I solve it myself (if I don’t know how to solder).
Or do you still have to cut through the molex?

Answer:

KARTEZ, buy a PWM splitter and connect as many turntables to CPU_Fan as you like.

Already bought, thanks

Q: Video card slot not working


In general, the computer does not turn on with the video card, most likely it happens short circuit. I've been trying to fix it for a month (I'd rather not try). And recently I discovered (using a flashlight) that there are no 2 pins (small metal rods) on the video card connector. Armed with a magnifying glass, I saw that one of them was stuck and broken, and the other was simply not there. I have a few questions.

1. Is my motherboard a kirdyk? And does it need to be changed?
2. Whether it is possible to rearrange the processor on other mother?
3. Is it possible to fix the motherboard at all?

(I can’t check the performance of the video card, or the continents with the help of donors (because there are none))

Answer: Odione, even if you have a PCI video card, insert it into another slot.
Are you sure it's the video card?
Motherboard model?

Message from Odione

PC won't turn on with graphics card

Does it turn on without a video card?

Question: Work USB-connectors on a netbook


Hi all!
This situation happened recently. Witnessed setting up a buggy program on a netbook. In the process of connecting the flash drive to the connector, the owner for some reason said that it was impossible to connect devices (mouse, flash drive) to the connectors on the right side of the netbook (as I understood it - in general).
I understand that perhaps the question sounds idiotic, but where did he get this from? I did not ask, because it was not easy to get into, but the question puzzled me. If a person says this, then something is behind it. Perhaps he does not understand something, perhaps I do, but what could be behind this?

Answer: Thanks to all. From everything I read, I conclude that there are no reasons other than possible malfunction or direct intervention in the iron here can not be.

Question: The chip stopped working, but the indicator works


Flash drive stopped working. The indicator on the flash drive itself works, the computer reacts with sound to its connection. All USB ports work - checked. I connected the flash drive to another computer, the same result.
I used a flash drive to watch movies on the TV - now the TV does not recognize it either.
After a breakdown, in the stop menu, the device with "Transcend (F:)" itself was renamed to "Generic USB Flash Disk USB Device (F:)"
I unchecked the folder option in the "do not show hidden files"- the flash drive became visible in the explorer, along with another obscure device with the name (I:)
When you try to open a USB flash drive through the right mouse button, it asks you to insert a disk into the device.
In Disk Management, the flash drive is also not visible, instead of Disk 1 and Disk 2, while, after removing the flash drive, one of the disks disappears and only Disk 1 remains.
I changed the drive letter several times, it didn’t help. In the properties of the flash drive, it says that the device is working fine
When I try to update the driver, it says Windows system determined that the drivers for this device do not need to be updated.
The device manager sees the USB flash drive, but also does not want to help me with anything.
I have already tried all the methods known to me, without using third party programs, but, apparently, I'm so stupid that I could not fix anything.
Therefore, I ask you to help - is there any way to save the device? What to do with it? help me please

If the solutions above did not help with the problem when USB 3.0 does not work on the computer, you should try restoring the computer to a previous working state. This can be done if you have activated a Windows restore point earlier.

Please write in the comments below if you managed to solve the problem with a faulty USB 3.0 port, and what solution worked in your situation.

USB is the most popular interface for connecting various peripherals to a computer. Its popularity is determined by the fact that it allows not only to perform the function of data exchange, but also powers the connected device. Keyboards, mice, Wi-Fi receivers, external hard drives and much more.

Table of contents:

What is USB 3.0

A logical step in the development of the USB interface is to increase the speed of device data exchange through it. Simply put, the higher the version of USB, the faster information is transferred through it. For devices such as a keyboard and mouse, this is not fundamentally important, but, for example, data transfer speed is of key importance when working with external storage media.

The USB 3.0 specification appeared on the market in 2008, that is, more than 10 years ago. Despite this, USB 3.0 is still not present on all devices. Much more common USB standard 2.0, which is significantly slower. The data transfer rate through the USB 3.0 protocol reaches 5 Gb / s, while for USB 2.0 this figure is at the level of 480 Mb / s.

We recommend reading:

Please note: To distinguish USB 2.0 from USB 3.0, you need to look at the connector. According to the accepted standard, the USB 3.0 connector has a blue baffle.

Error "This device can run faster when connected to USB 3.0"

One of the errors that a user may encounter if there is a USB connectors 3.0, reads as follows: "This device can run faster when connected to Super-Speed ​​USB 3.0." The error indicates that the user has the ability to transfer data from the connected device faster than he does now, if you use the USB 3.0 interface.

This message is not an error, but rather a tip for the user to use a faster port, and it is correct if it appears when the device from which the data will be transferred was connected to USB 2.0 while USB 3.0 is available. But, often, such an informational message occurs when the peripherals were connected to USB 3.0, that is, in desired port, but Windows cannot determine this.

How to fix "This device can run faster" error

If a device is connected to USB 3.0, but you still receive a notification that this device can run faster, this indicates that there are obstacles in the BIOS or Windows to determine the interface.

BIOS settings

If in settingsBIOS not set what portsUSB 3.0 should work in high-speed mode, they will work in the standard USB 2.0 Usually, this is the problem that leads to the error "This device can run faster." Do the following:


To understand this procedure, it is necessary to explain what the XHCI parameter is. XHCI itself is USB controller 3.0. When it is turned on / off, the fact of interface support changes accordingly motherboard. Not all BIOS versions have a separate item responsible for USB support 3.0, and in such cases it is necessary to focus on the values ​​of the XHCI parameter, which, in addition to the "Disable" and "Enable" options, can also be "Auto" and "Smart Auto".

Please note: If the parameterXHCI exhibited one of automatic modes, this means that at the time of booting the computer, before startingWindows interfaces will work in modeUSB 2.0, and after starting the operating system in the modeUSB 3.0

Windows Driver Update

If the BIOS is configured correctly, you need to make sure that there are no problems with the USB 3.0 drivers. In a regular situation, they are installed automatically and there are no problems with them. But, for example, if the distribution kit from which Windows was installed is “broken” or some problems occur during the operation of the system itself, the USB 3.0 driver may no longer be detected.

Despite the widespread cloud technologies and increase the speed of data transfer over the Internet, removable USB media information is still actively used in working with computers. Flash drives latest generation transfer large amounts of information at a significant speed and do not depend on the connection, provider and network restrictions. This article describes the most common causes why the personal computer does not see USB flash drive, and provides instructions for solving these problems.

Physical problem with flash drive

This is not the most common, but the most obvious reason why the computer does not see the flash drive. Inside these devices are microcircuits, which, like any other electronics, can burn out. It is possible that water got inside the case and caused the contacts to close. Also, due to improper operation, one of the contacts of the plug could be damaged.

There are even special viruses, which burn all devices plugged into a specific USB port personal computer. In this case, nothing can be done to help.

Physical problem with the port

Another obvious reason why the computer does not see the USB flash drive lies in problems with the port itself on the computer. The condensate that got inside it could oxidize the contacts, which leads to the loss of their performance. The port may have burned out due to power outages and unstable power supply.

Also similar problem may occur if the port is not connected to the motherboard. Similar situations often happen in the case of the front panel of a PC case. The controls and ports located on it must be additionally connected to the motherboard. If the wire came off, or they simply forgot to connect it, nothing will work.

In this case, it is worth checking the wiring inside system block or contact an assembly specialist.

Drivers for USB 3.0

Not so long ago, the USB 3.0 generation that came into use has not yet completely conquered the market. Typically, such ports are installed in cases along with the still relevant, but slower 2.0. They can be identified by the blue strip of plastic inside the connector itself.

The problem may be that the BIOS version you are using or the “clean” installed operating system has only the second generation drivers installed. Normal ports in this case work in normal mode, and the "blue" ones will not show any signs of life.

The problem is solved by installing drivers on your motherboard. They can be found on the included DVD or downloaded from the official website of the product manufacturer. You can also try updating operating system– Master windows updates independently pulls up and installs all the necessary patches.

Reinstalling drivers

If you are sure that your ports and a portable device are working, which for some reason the computer does not read, you can try reinstalling the driver on the USB port. Extreme care is recommended when handling installed drivers. Incorrect actions can disrupt the stable operation of the OS. It is best to create a Windows restore point before following this guide.


The necessary drivers will be automatically installed on your computer.

Virus infection

If the PC or laptop does not detect the USB flash drive, the problem may lie in some malicious code. First, a script may be running on the computer itself that interferes with correct operation controllers or Windows Explorer. To solve this problem, you need to scan the system for viruses and clean it. This is done using special programs- antiviruses.

If you do not have an antivirus installed, it is highly recommended to download it. you can use free utility from Microsoft - Security Essentials, which can be downloaded from this link https://www.microsoft.com/en-us/download/details.aspx?id=5201.

Install the program and run it. Select "Full" from the options menu on the right and click the "Check Now" button. After that, you will need to wait a while while the utility looks for malicious scripts on your system.

Another problem may be that viruses have infected your removable device, and installed on your computer antivirus program blocks an infected flash drive. In this case, the PC detects the media, but will not work with it until it is cleared. Wait for a while while the antivirus prepares the device for safe operation.

System Configurations

The problem that the PC does not read the flash drive can be caused by specific settings in your Windows. You can change them by editing the entries in system registry:
