Sees a mouse but doesn't work. The computer does not see the mouse: causes and methods of troubleshooting

Oh, those computers, there's always something to do. Back in the days when instead of the Internet there were BBS (Bulletin Board System), replacing the current chats, social networks and file dumps, I said that the computer can be given all the time that you have. And now, with the ubiquitous dominance of the Internet, this topic is even more relevant. And it is also surprising how some seemingly elementary things, if you call the computer for help, take not at all elementary time. It was a saying. And the fairy tale is ahead.

Let's start from afar. As you all know, a computer without input devices such as a keyboard and mouse can have a touchscreen (and some also have a joystick) - a simple piece of hardware that buzzes and consumes electricity. I got a computer that needed to be looked at and slightly reanimated after a virus frolicked there. I took out a spare monitor from the shelf, plugged in a spare keyboard, a spare USB mouse (this is important), turned it on, climbed BIOS settings(basic input-output system), booted Windows and shit, the mouse turned off. I just worked in the BIOS, the pointer was running like that, and after Windows boot does not work. What the heck?

We know that there are at least two common types of mice (computer), differing in the connection connector. These are PS / 2 and USB. If the first option is used primarily on stationary computers, then the second one can be used everywhere, even connect to modern smartphones... And what is important A, the USB connector can be turned on and off in hot mode, ie. when the computer is on, but if you have a PS / 2 connector, it is better not to risk it, as it may simply burn out. Better to turn off your computer and then plug and unplug connectors. Older computers had two PS / 2 connectors that were different in color. Green is for the mouse and purple for the keyboard. Now there may be only one, or even none.

Let's go back to my computer. Symptoms are as follows: The mouse is completely functional, it works until the operating system is loaded, it works on another computer all the time, i.e. the case is in Windows. The USB port also works, if you connect a keyboard or flash drive to it, then everything is fine. The other USB mouse also does not work. The PS / 2 mouse, on the other hand, works fine. When connected to another USB connector, the system writes that a device was found, the driver is installed, the driver is successfully installed, but the mouse also does not work.

We look at devices through the device manager. Here we are interested in Mice and other pointing devices. If we do not see our mouse in the tab, then there is a problem with the driver *. And another problem is that USB mice are so standard that a special driver is not needed and is already on the list of standard ones. We connect the mouse, we see that something new has appeared in the section HID devices, therefore, the mouse is not recognized as a mouse, but as something else. In this case, it does not matter which USB port the mouse is plugged into. Will not work. To fix the situation, you need to manually change the driver on the HID device. From context menu HID device select Update Drivers-> Find and Install Drivers Manually-> Select From installed drivers-> HID compatible mouse

After that, the USB mouse appears in the mouse list and starts working. Even after disconnecting-reconnecting and restarting the computer.

* Driver - a program that allows you to directly control the device in the operating system. Since the operating system does not know about all the variety of devices, for full-fledged operation, device manufacturers release a driver that becomes an intermediate layer between the device and the operating system. If the device is standard, then a special driver is not needed, it is already included in the operating system.

A computer mouse is an integral part of the system. Some people have such a case when the mouse either starts to work poorly or completely fails, and in Windows this thing is very necessary. I think many people have asked the question, is it possible to somehow fix the mouse, or just fix the problems in the system due to which it does not work? Of course you can, and now we will try to resolve this issue.

If the mouse does not react at all to any actions, many immediately run to the store for a new one, although the rest solve this problem on their own, which leads to the long-term service of the manipulator.

Many of you probably know that there are several types of connecting the pointing device to a computer or laptop - PS / 2, USB, Bluetooth and Wi-Fi. Thus, the first two are wired keypads, and the second two are wireless. Everyone can have their own malfunction.

Troubleshooting recommendations for all manipulators

What if the mouse still works, but is unstable, for example, it turns off and then turns on again?

When connecting the pointing device via USB, it is worth taking another USB wire... If your operating system has been installed on your computer for a very long time and has not been updated, then this can cause unstable operation of the manipulator, it is also possible that many other manipulators were connected to the computer, as a result of which there was a conflict between the drivers.

Try plugging the mouse into a jack on another computer and if everything works well, then the problem is with the USB controller.

You can try to reinstall the mouse driver using the keyboard, for this you press the Win + R combinations and enter the command mmc devmgmt.msc .

We got to the device manager. Now you need to press the key Tab so that you can navigate using the arrows. Scroll down arrow to point "Mice and other pointing devices" to expand the list press the arrow to the right.

Move to the desired device and press Enter, a window will open where you need to hold down the Ctrl and Shift keys, and then pressing the Tab key to move to the tab "Driver", after that just press the button "Tab" and move to the button "Delete"... Press Enter and confirm the action.

Restart your computer or laptop, and then re-insert the mouse, the driver should be reinstalled and, perhaps, everything will work.

What if the manipulator cursor is not stationary?

This is not such a difficult problem, perhaps the sensor is clogged with dirt, dust, something stuck and prevents the cursor from hovering over objects normally. I advise you to wipe the mouse completely, starting with the sensor.

The next problem is that the buttons of the manipulator are almost unresponsive when pressed, what should I do?

Here the problem is already associated with the mouse itself, that is, at the hardware level. It is possible that due to the large number of pressing, the button or buttons failed, or you pressed them so hard that they went out of order due to your fault. There is an option that dirt got inside and this does not allow the button to function normally, you will have to disassemble the mouse and see. If no dirt is found, then most likely it is necessary to replace the micro button, which requires appropriate knowledge.

Several individual problems for manipulators

If you have a wired keypad, then common causes of failure are related to the wire that is kinked or torn. Examine the cable carefully for damage.

What should I do if my wireless mouse doesn't work? If these types of manipulators operate on batteries, then it is quite possible that they are dead. Replace them. If the problem is not related to food, then you will have to look for the problem yourself. Some of the types of problems described above may apply to wireless keypads as well.

Another disadvantage of wireless pointing devices is that they can conflict with similar frequencies of other devices, it can be anything - a smartphone, tablet, TV, refrigerator, router, etc.

The most important problem for computer mice is that many of them are not shockproof, if you dropped the mouse a couple of times, then do not be surprised that it is out of order or does not work well. Not every manufacturer uses high-quality parts for the manufacture of a manipulator, so take good care of things.

This is the end of this article. If you have any questions, do not hesitate to ask them.

Modern mice are accurate and durable. Yet one day the computer may not respond to mouse movement.

The computer does not see the mouse: causes and methods of troubleshooting

Faulty USB port

The reasons for the inoperability of the USB port are similar for all PCs running Windows.

For Apple computers Mac operations are more straightforward.

Make sure the USB port is working. Insert a working mouse or flash drive into the USB socket. The flash drive will blink - it means that USB port worker, no - he's damaged. If the USB port works, do the following.
Check macOS system for viruses. If you find software problems, reinstall MacOS, check your PC for viruses.
Reinstall MacOS USB drivers. Apple PCs must come with chipset drivers. You can find them at apple.com.
In the event of a USB port malfunction, contact an Apple Service Center - unlike other computers, Macs are quite difficult to disassemble, so it's better not to risk it yourself. It may happen that not only the USB port is faulty, but also the south bridge of the main board of the computer.
If the USB port has nothing to do with it, most likely the mouse itself does not work. Buy a new Apple mouse or equivalent.

Defective mouse cable

Shorting two or more wires of the cable together, breaking any of the wires. The USB interface is designed in such a way that all five "cores" - "+", "-", "data +" and "data-" and shielding should not be violated. A break in any of these wires is guaranteed to lead to inoperability not only of the mouse, but of any device in general. It happens that due to the lack of a replacement for a damaged cable, a new mouse is required.

The mouse is damaged

The old-style mice, widespread in the 90s and the first half of the 2000s, were optical-mechanical: in addition to a light and photocell, a controller and a reader, they had a mechanical drive - a ball, rollers and a slot breaker. Now such mice have become a rarity - they have become purely optical.

This is what a disassembled mouse looks like.

In addition to a faulty cable, malfunctions of the mouse can be as follows:

the main board does not work (controller, reader, light and photocells);
the lens is dirty or scratched (rarely, but it happens);
the wheel control unit is faulty;
the buttons are faulty (the mouse pointer moves on the screen, but the commands from the buttons and the wheel - it also has a third button - do not pass).

Wireless mice are powered by one or two replaceable batteries or rechargeable batteries. Defective here can also be:

pressure contacts (if they are of poor quality, they can oxidize or rust);
power wires;
a wireless module that provides communication with a USB device (it can be several times smaller than a USB flash drive);
batteries (expired - replace them) or rechargeable batteries (empty, need to be charged).

If the boards and controllers break down, the mouse must definitely be replaced.

Problems with mouse operation at the software level

Understanding Driver Problems

Incompatibility of the chipset drivers after replacing the Windows version with a newer one (or, conversely, an old one) may result in a mouse control failure. Since the mouse / touchpad / sensor driver is usually included with all modern operating systems except MS-DOS, the main reason for mouse failure is considered to be inoperability. USB driver: This component is Universal Serial Bus Controller and USB Root Hub. Search the Net for the version of the chipset driver that matches that version operating system which you are currently using. However, in Windows versions 8 / 8.1 / 10, all the main chipset drivers are already system components - they do not have to be installed separately.

For Apple computers (for example, MacBooks), mouse and touchpad drivers are also included with macOS - when updating a version of macOS, say, from Yosemite or El Capitan to Sierra, the mouse problem concerns only the lack of computer performance in the latest version of macOS. Wireless mice like Magic Mouse, however, require a separate setup - they require a Bluetooth driver for MacOS to work.

So, on Acer netbooks recommended for work with Windows 7, with Windows installation 8 / 8.1 / 10 there was a problem with the hardware of the netbook - the versions of the chipset drivers for Windows 7 did not fit: the sensor stopped working (the mouse pointer did not respond), the wireless disappeared network connection etc. The best solution was to ignore these outdated drivers - after uninstalling them and restarting Windows, the missing devices worked fine again.

All this suggests that in latest versions operating systems, be it Windows or Mac, developers of graphic shells have taken into account and supported at the software level almost all functional blocks and nodes of a PC. For this, a timely update is needed.

Diagnose USB ports on Windows PC

To reset USB controllers on your Windows PC or laptop, do the following.

If resetting and re-registering USB controllers after restarting Windows did not work, then the problem is different, for example, in the USB setup.

Diagnose USB ports on Mac

On MAC computers to regain control of the USB ports - and with them mouse control, reset the SMC (System Management Controller) parameters. For different models Mac PC reset method is different.

On a MacBook with no removable battery follow the steps below.

Turn off your PC.
Connect the MagSafe or USB-C power adapter to the power adapter and to your PC.
Press the keyboard shortcut: Shift + Control + Option (left) and the power button.
Release all keys and the power button.
Turn on your PC.

For Mac laptops with a removable battery, do the following:

Turn off your PC, disconnect the MagSafe adapter from your PC, remove the battery.
Hold the power supply for a few seconds.
Connect the battery and MagSafe adapter and turn on your PC.

On Mac Pro, iMac, and Mac mini

Turn off your PC
Unplug the power cord, wait 15 seconds, plug it back in.
Wait another 5 seconds and turn on your PC.

Troubleshoot a wireless mouse on Mac

Bluetooth mice are widespread. Apple's Magic Mouse is taken as an example. You also need another USB mouse. To test Bluetooth communication, do the following.

After reconnecting, Magic Mouse should work again. If the problem recurs, it is possible that bluetooth device it works incorrectly. Reinstall the Bluetooth driver. If all else fails, even a "clean" installation of MacOS - perhaps bluetooth module or the Magic Mouse itself is defective. Contact Apple for troubleshooting.

Incorrect USB setup in Windows

Automatic shutdown of USB ports is one of the protective measures against overconsumption of electricity to power the computer and against excessive overheating. Unused in this moment ports are suspended. Disable this in Windows Power Options.

Although modern USB controllers supply power and control signals to the interface as soon as any device is connected, the port may not respond in time to the mouse connection. Linux, Windows, or MacOS are not immune to USB failures.

Checking USB controllers in Linux

The Linux operating system also allows you to manage USB ports on your PC. Supported different versions USB interface, including 2.0. Let's take the Linux Gnome Ubuntu graphical shell as an example.

The lspci command, entered in the Linux terminal, allows you to display USB devices... For example, let's take three USB controllers installed on a PC running Linux.

[email protected]: ~: # lspci grep -i usb

00: 03.0 USB Controller: Silicon Integrated Systems USB 1.1 Controller (rev 0f)

00: 03.1 USB Controller: Silicon Integrated Systems USB 1.1 Controller (rev 0f)

00: 03.3 USB Controller: Silicon Integrated Systems USB 2.0 Controller

Now enter the lsmod command. For example, it will come out like this:

Module Size Used by

hid_microsoft 3232 0 usbhid 32992 0

hid_microsoft, usb

hid ohci_hcd 24332 0

ssb 38464 1 ohci_hcd

ehci_hcd 34152 0

Be sure to check if your mouse is among the connected devices.

Other USB software crashes on any PC

Anything can disrupt the operation of USB ports - from improperly installed drivers to viruses that launch unnecessary copies of system processes and overload the computer's performance. MacOS is one of the most protected operating systems from any Internet threats.

Mouse problems on the tablet

Modern tablets based on Windows and Android also support mouse operation via Bluetooth or via an OTG USB-microUSB adapter, to which both a classic mouse with a USB cable and a module from wireless mouse... Indeed, on a large, 10-inch screen, using a mouse along with a keyboard when placing the tablet on a special stand is already relevant.

For Windows tablets, follow the same steps as for a Windows PC or laptop.

On tablets with Android in the current version of the operating system Android systems there must be system libraries that support mouse control of the tablet. If the pointer (or marker) does not appear on the display and there are no signs of controlling the tablet with the mouse, you may need to flash the Android system with official version to "custom" with replacement android kernels or installing a special application for controlling the tablet with a mouse.

As for the performance of the microUSB ports, you cannot do without checking. First, check the OTG adapter itself - it is desirable to have at least two working adapters. If the suspicion still falls on the microUSB port, connect a keyboard (you can wireless), a 3G / 4G modem, a USB flash drive, a printer or something like that instead of a mouse. Try connecting two or three devices at once through a USB hub with external power supply... You will hardly fail to notice that the microUSB port is faulty. In this case, you cannot do without specialists from a “mobile” or computer service center.

Finding out why the mouse does not work is a task of ingenuity, which, however, you can solve by yourself, contacting specialists only in case of emergency. You will succeed!
