Oh, that's it, I found the utility UPTool_Ver2093(Release)_20150312. I'll try it right now!

Added after 14 hours 25 minutes
That's it, it worked
qvad, thank you for the tip. But I don’t understand what this program did to flash the flash drive? It wrote that it was running Low Level Format ( Low-level formatting). Please explain what happens during low-level formatting?
As I understand it, all cells of the microcircuit are checked with flash memories and when broken cells are found, they are somehow blocked by entering the numbers of these broken cells into the EPPROM memory firmware of the controller? Am I thinking correctly, or am I being stupid out of the blue? Thank you!

Question: z575 (LZ575 MB 48.4M502.011) keyboard does not work

It doesn’t work, neither the original one, nor the new one, nor via USB, but this is only in Windows. Anyone can respond to F2, but then you are asked to enter a password that no one knows or remembers. It’s clear that you can upload a dump, but the laptop is still lying in front of me undisassembled, and I don’t want to pick it yet) Has anyone encountered this kind of behavior?
The mouse works, the flash drives work, but the touchpad also doesn’t want to work at all, but its function may be disabled. key... The drivers are all present.

Answer: The new cartoon didn’t help... I don’t know what to do anymore. The keyboard has been checked, the tracks have rung, the connector too... And it works in the BIOS too
I found a thread, it looks like the same thing. Yes, that is right.

Question: The flash drive flew off

Hello, just 20 minutes ago the flash drive was working. When I installed Windows 7, I needed to convert drive C (from MBR to GPT) to another format through the console and format it accordingly. Instead of formatting drive C, I I took it by chance and formatted my flash drive (16 gb) through the console and converted it to GPT format and my Windows installation 7 ended sadly because I formatted the flash drive with my Windows. Now it doesn't work, when I insert it into the port, it lights up, everything is fine and the computer shows that new hardware has been found, but when I go to "My Computer" it is not there. Help solve this problem. The flash drive should essentially work.

Answer: There is no such thing at all, only Unallocated -> New Simple Volume is there.

Thanks, I figured it out, everything works.

Question: The fan power connector on the video card does not work

Hi all.
I encountered this problem...
Video card

Has a system of 2 fans (3 pin (blue red black) and 4 pin (blue red black yellow))
They are connected through an adapter into one and then go to the 4-pin connector on the video card...

So, the problem is that this makes the connectors not spin, although they spin from the connector on the motherboard...

How is this done? is it worth fixing?
or solder on Molex and not worry?

Answer:

Solder on Molex and not worry?

I would do just that... just in case -

Question: Bios does not recognize the USB 3.0 flash drive

Motherboard MSI 880GMA-E45 (MS-7623). The BIOS version is the latest that is on the manufacturer's website. Tell me what the problem is? The flash drive works fine under the operating system. And when loading, the BIOS does not see it, but when I change it to connector 2.0 everything is fine determined...Flash Transcend 16GB

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

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

Question: The connector for the ventilator does not work

Such a mother
I bought a used one, 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 doesn’t work, I tried different coolers. What is the problem, why do you have to solder? I don’t want to take it in for repairs just for the sake of such a small thing, can I figure it out myself (if I don’t know how to solder)?
Or will I still have to cut it through Molex?

Answer:

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

Already bought it, thanks)

Question: The video card connector does not work

In general, the computer does not turn on with the video card, most likely this is happening short circuit. I've been trying to fix it for a month (I'd rather not try). And I recently discovered (with the help of a flashlight) that there are no 2 contacts (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 missing. I have a few questions.

1. Is my mother bad? And does it need to be changed?
2. Is it possible to move the processor to another mother?
3. Is it even possible to fix the motherboard?

(I can’t check the performance of the video card or mainland using 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 a video card?
Model motherboard?

Message from Odione

Computer won't turn on with video card

Does it turn on without a video card?

Question: How do USB connectors work on a netbook?

Hi all!
This situation happened recently. I 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 the connectors on right side You cannot connect devices (mouse, flash drive) to a netbook (as I understand it - at all).
I understand that the question may sound idiotic, but where did he get it from? I didn’t ask because it was too much for me to do, but the question puzzled me. If a person says this, it means there is something behind it. Perhaps he doesn’t understand something, perhaps I don’t, but what could be behind this?

Answer: Thanks to all. From everything I’ve read, I conclude that there are no reasons other than possible malfunction or there can be no direct intervention in the hardware.

Question: The chip has stopped working, but the indicator is working

The flash drive stopped working. The indicator on the flash drive itself works, the computer responds with a 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 TV - now the TV doesn’t 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:)"
Unchecked the folders option under "do not show" hidden files" - the flash drive became visible in Explorer, along with another incomprehensible device with the name (I:)
When I try to open the flash drive through right button mouse - asks to insert a disk into the device.
In Disk Management, the flash drive is also not visible, instead it is Disk 1 and Disk 2, and 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 drivers, it says that the Windows system has determined that the drivers for this device do not need to be updated.
The device manager sees the flash drive, but also does not want to help me.
I have already tried all the methods known to me, without using third party programs, but apparently I’m so stupid that I couldn’t fix anything.
Therefore, I ask you to help - is there any way to save the device? What to do about it? help me please

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, and Wi-Fi receivers, external hard disks 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 USB version, the faster information transmitted through it. For devices such as a keyboard and mouse, this is not fundamentally important, but, for example, data transfer speed is key when working with external media information.

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. The much more common standard is USB 2.0, which is significantly slower. The data transfer speed via the USB 3.0 protocol reaches 5 Gbit/s, while for USB 2.0 this figure is at the level of 480 Mbit/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 partition color.

Error "This device may perform 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: “This device can perform 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 can now if he uses the USB 3.0 interface.

This message is not an error, but more like advice for the user to use a faster port, and this is correct if it appears when the device from which data will be transferred was connected to USB 2.0 when USB 3.0 is available. But, often, such an information message appears when the peripheral was connected to USB 3.0, that is, to the desired port, but Windows cannot determine this.

How to fix the “This device can run faster” error

If a device is connected to USB 3.0, but still receives a notification that this device can run faster, this indicates that there is an obstacle in the BIOS or Windows to detect the interface.

BIOS Settings

If in the settingsBIOS is not set, what portsUSB 3.0 should work in high speed mode, they will work in standard USB 2.0. Typically, this is the problem that causes the “This device can run faster” error to appear. Follow these steps:

To understand this procedure, you need to explain what the XHCI parameter is. XHCI itself is a USB 3.0 controller. When you turn it on/off, the fact of interface support changes accordingly motherboard. Not at all BIOS versions there is a separate item responsible for USB support 3.0, and in such cases you need to focus specifically 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 is one of the automatic modes, this means that at the moment the computer boots, before startingWindows interfaces will operate inUSB 2.0, and after starting the operating system inUSB 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 normal situation, they are installed automatically and no problems arise with them. But, for example, if the distribution from which Windows was installed is “broken” or certain problems arose during the operation of the system itself, USB driver 3.0 may no longer be detected.

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

It doesn't work for only one reason: drivers for USB 3.0 are not installed on the system.

To check the presence of drivers in the system, look in the device manager to see if there are any questions or 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. As an option, I uploaded USB 3.0 drivers for the motherboard to my server Intel boards, AMD and Asus. You need to download one of the presented drivers.

How to find out what motherboard you have?

Laptops usually have an INTEL or AMD type label.

In Device Manager under USB controllers pay attention to the following inscriptions:

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

2. Download the program DriverPack Solution, then install or update the USB 3.0 driver. The program is absolutely free and does not require installation, but this 1 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 purchased the computer, or use my article “ Where to download drivers" In this article, I showed how to download firewood from the official websites of such manufacturers as Acer, Samsung, Toshiba and Dell. A video is attached to the article.

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

Hello everyone Let's talk about flash drives, or rather about their compatibility. So I’ll write it this way, without going too deep into the terms, so that it’s clear to you and so as not to overwhelm you. So what is a flash drive? This is a storage device. In order for the data to get there, you need a cable, well, a connector, a port. This is roughly an interface. But for maximum comfort, the data must be transferred to the flash drive as quickly as possible, as well as read from it. They are constantly working on this, coming up with new data transmission standards.

Today, well, in 2016, the most popular revision is both USB 3.0 and USB 2.0, it may be that the latter is even popular. These versions differ mainly in speed and current strength. These are the two main differences. So what can I say here, I can only make you happy, because versions USB 2.0 and USB 3.0 are completely compatible!

That is USB flash drive 3.0 will work smoothly in a USB 2.0 connector and vice versa. However, what is important to understand is that all this will work for USB speed 2.0, to be honest, I don’t remember how much speed there is, but still in reality it’s less than they write. I will say for myself that version 3.0 feels two to three times faster than 2.0, but the characteristics are even greater.

Speed ​​is one thing, but there is also such a thing as current strength, this is where it gets a little more interesting. USB version 2.0 can provide up to 500 mA, and version 3.0 up to 900 mA, both have a voltage of 5V. But the main thing here is that modern hard drives, well, those that are connected via USB interface 3.0, then I don’t know how they will work if they are connected to port 2.0. They may work well, or they may not. For hard drives High-quality and stable nutrition is very important. In general, this point is important and you need to take it into account; the same applies to recharging from USB ports. Check if there are any problems, look for information on the Internet, this is just my advice to you

As you can see, speed is one thing and it mostly concerns flash drives, but for other USB devices, this is a bit serious. It's better to consult. Personally, if I wasn’t sure, I wouldn’t connect HDD USB 3.0 to port 2.0, you never know...
