The printer writes the device is not identified. Turning off the temporary shutdown parameter of the USB port

The HP printer does not see the computer. what to do?

As in the case of any computer technology, in printers and multifunctional devices (All-in-One Printer) HP may arise, which leads to the impossibility of working with it through a computer. Many malfunctions can be eliminated independently, but others. only with the help of specialists or the presence of certain skills in the repair of such equipment.

In printers connected to a computer via a USB cable, the same problems as any other USB device arise mainly. over, some of them are not directly related to the printer itself. Here is a list of the main reasons leading to the impossibility of determining the printer by a computer:

• Damage to the USB cable.
• Lack or malfunctioning the printer driver.
• Problems in the operating system software (in addition to drivers).
• Malfunctions in the work of built.in software (firmware) printer.

We will not consider the possible hardware malfunctions of the printers and the All-in-One Printer HP-there are quite a lot of things, and their elimination is practically unrealistic without the help of specialists.

Damage to the USB cable

First of all, we recommend that you verify the operability of the USB cable. It is quite banal and at the same time very often encountered malfunction. If it works, then when connecting the printer to the computer, a sound signal will be heard, indicating the detection of the connected device system. But this is an inaccurate way. If at least one of the wires is damaged in the USB cable, then the computer can still issue a signal about connecting the device.

To make sure that there are no problems with the cable (or vice versa), it should be checked on another printer or any USB device with a similar design of a USB port (usually it is a square shape). If this is not possible, then it remains either to find a deliberately working USB cable, or check the existing with the help of the multimeter (you can even, for example, assemble a home-made tester from the battery and the LED to check the integrity of the cable wires). Unfortunately, there are no other options.

However, it is always possible to connect the printer through a USB cable, but over the network. Depending on the specific model of the HP printer, this can be done both through a network cable and through a wireless Wi-Fi connection.

Connection of the HP printer via Wi-Fi with a faulty USB cable

Consider only the simplest way to connect the printer through Wi-Fi. The method is applicable to those HP printer models that support WPS technology (Wi-Fi Protected Setup-Automatic connection of devices to a Wi-Fi Router). The existing wireless router should also support WPS (most Wi-Fi Routers support this technology). This can be checked by examining the router housing. It should have a button designated as “WPS” or with this icon:

• Press and hold the “Wireless Communication” button on the device case, designated as “Wi-Fi” or the corresponding icon, until one of the following LED indicators: “Wi-Fi” (HP Tango), “Wi-Fi “And” Food “at the same time (HP jet printers),” attention “(laser printers of HP),” condition “(purple indicator present in some All-In-One Printer HP-Envy 6000, Deskjet Plus IA 6000, etc.).
• Now, click and hold the WPS button on the Wi-Fi-Root, while the Wi-Fi indicator (or one of those that was discussed) on the All-in-One Printer case will not light up stably. In some cases, you will have to hold the button on the router for 2 minutes (depending on the model of the router and the printer itself).
• As soon as the Wi-Fi connection between the router and the printer is installed, the latter will remain to add to the system. To do this, open the “control” panel from the “Start” menu, go to the “Equipment and Sound” section, then open the “Devices and Printers” subsection. At the top of the window, click on the “Add printer” button.
• For some time, Windows will search for the printer. If she succeeds, the name of the device will be displayed in the new window. It remains only to click on it, and then follow the instructions on the screen.

If the existing HP printer does not support work through Wi-Fi, then due to lack of USB cable, it remains only to find LAN cable (t.e. An ordinary network cable, compressed by standard LAN connectors on both sides). It must be connected to the LAN port of the computer and the printer itself, and then add to the system, having completed the last two steps from the instructions above.

The reasons

Thought to see the serious reasons for your mistake here? Yes, as if not so) if seriously, each case is unique in its own. But the general methods of elimination that were checked in the case when the computer does not recognize the USB device, you will see here. Only the main reasons are listed below. Your case may be unique!

And yes-if you solve the problem somehow in their own way, I strongly recommend writing about this in the Комментарии и мнения владельцев. Remember how long you have been looking for a solution, think that someone can save your nerves. Helping each other!

• Curves drivers (including the problem of incompatibility of the driver with your version of the OS, for example, the old device does not want to work on Windows 10).
• Problems with nutrition.
• A device or cable has broken (be sure to check your device and cable on another computer).

We correct the error

These methods will mainly help for connecting flash drives or hard drives on USB 2.0 or 3.0. Problems with a broken cable or physical breakdown in this section are not solved. I first recommend diagnosing your device on another computer.

I try to list all the current ways below, what to make solutions to this problem. Something you will succeed, something. We try, do it, do not know.

Primary actions

If you got an error for the first time, we try banal methods based on a physical connection:

• Connect the device to another USB port. Especially if you initially connected to the front ports, connect to the rear. on the front ports you may lack power. This is an old famous problem. And even more so if you use bakers, it is better to connect directly.
• Disconnect temporarily another unnecessary USB equipment. like a webcam, microphones, printers, scanners. Try connecting without them.
• Now in fashion for the nature of different ports. USB 3.0 and USB 2.0, which are outwardly identical and, in fact, are back compatible. But in some cases it still doesn’t work. If you have different versions of the ports, we try to poke in all.
• Reboot the computer-yes, for some reason, many are shy about just rebooting.

Trite? Yes. But 95% of cases these four steps calmly close. If it did not help, I recommend connecting the same device to another computer or laptop. will it work at all? So it can be determined that the problem is specifically in a computer gland or depends exclusively on the software (usually drivers, updates).

Drivers. search

Not always, but as a rule, the error flies because of the impossibility of picking up the driver or even due to its absence. Of course, your case may be different. But I would still check. I will show actions below with the example of Windows 10, but if you have something else-look for analogies yourself.

• Here we look at suspicious devices. Usually they are highlighted in some sign in the spirit of the yellow triangle. Take a closer look! Most likely this is your device. We click on it with the right mouse button and select “Update the driver”. “Automatic search for drivers”:

The search will occur without your participation (the Internet must be connected). Some such banal automation helps. And it helped you? If not, we are going further.

It works especially well with an error code 43. If you wish, you can look for a driver not automatic method, but pitch it manually among the installed or even download from the official website.

You can also use automatic third.party driver installers. Personally, I prefer Driver Pack Solution, but there are really a lot of others (look for only free solutions). The main minus DRP-during installation, he will try to install some extra software to you. Therefore, only the administrator regime in the program and a thorough check of all checkmarks, then all the drivers are updated simply remarkably.

This is more from personal experience. I had one disk on my family drivers of the manufacturer. But after installing the “dozens” (and she likes to pull the last drivers). got up tightly. History conclusion: Sometimes you do not need to put the latest drivers, and only a specific version is suitable. Usually the manufacturer writes this (but not always). Therefore, for experiments, you can download the driver to be older and test it.

Drivers. rollback

You can still try to roll back the existing driver. what if it was established incorrect, then it is better to remove it completely.

• We go to the same dispatcher device. Also click on our device with the right button, but this time select “Properties”. We go to the “driver” tab and click “Rake”:
• If your device also can not roll back, you can try to remove it (button a little below). Do not worry, after rebooting the computer, he will find it again and try to install the driver.

As a note. The removal method works cool when you need to install the driver manually. T.e. You have already downloaded the installation program, but the system has put something wrong without you, and now nothing works. Then we do this. turn off the Internet (so that nothing is downloaded), roll back the drivers (until the button lights up gray, you may have to repeat several times), and at the end we delete and reboot the system. After such a reboot, you can start installing anew. Sometimes you can just try to put the driver from above, but the removal always works flawlessly.

Power control

In very some cases))) the essence of the problem. USB concentrators turn off the power, and as a result, the lack of power leads to the indicated problem. Which at the very beginning and asked to poke different ports. Here you can turn off this shutdown function.

• We go to the device manager again. But this time we choose not your problematic device, but a root USB concentrator (well, or something similar, if desired, the operation can be repeated at all for all controllers, nothing terrible will happen). We click on it with the right mouse button, select the properties, and then go to the “Power Management Management” tab:

Power supply. part 2

This case is especially applicable for USB 3.0 under the control of Windows 10. Another possibility of Windows itself disconnect USB port power. Let’s try to fix it.

• You need to get into the “power” window. If you are behind the laptop and see the battery icon near the clock. you can click on it. Otherwise, there is also a search for the system (but you can get to the bottom of this point and through parameters or control panel). As a result, such a window should open:

4 Check updates

Check if updates are available for your computer. If updates are available, Windows will also install the latest available computer drivers.

• Click on the Start button icon Parameters Update and Safety.
• On the screen, update and safety, click on the Windows update center in the side menu, and then click on the button checking the availability of updates.
• Let Windows check the availability of updates and install them on your computer.

If updates are available, the latest updates of the devices will also be installed on the computer.

Method Change Settings for USB

• Click with the right mouse button to “Start” and select the “control panel”.
• Select “power”, and then select the “high performance” plan.
• Press the button “Settleing SCOMMENT” next to your power circuit.
• Next, click on “Change additional power parameters”.
• Expand the Catalog “USB Parameters”.
• Insert the following parameters in it:

• From the battery: prohibited
• From the network: prohibited

We hope that the above methods helped you deal with the error “USB device is not identified“.

Settlement failure

Check which equipment is used to print by default. To do this, go to the control panel, then to “Equipment and Sound”. “View devices and printers”. Click on the printer icon with a right button and select the option “Use by default”. In some cases, this is enough for the device to work correctly.

If the problem has not been solved, click on the equipment icon twice, in the window that opens, select the Printer tab and remove the checkboxes in the “Put the Seal” and “Work Autonomously”. Also click on “Clean the Print turn”.

If this did not help, go to the control panel, select the “Small Bades” item in the “View” menu, go to the “Administration” tab and open the “Services”. In the window that appears, you need to find the “Print Manager” service and install an automatic launch type.

If the service is stopped, also click on the “run” button, and then send a test page to print.

Lack of driver

It happens that the computer does not see the printer via USB due to the lack of a driver either due to incorrectly installed or outdated software.

Go to the official website of the manufacturer, download the driver from there for your device and install it. Then restart the computer and try to print a test page.

If you accidentally installed an inappropriate driver, go through the Device Manager through the control panel, find the right equipment there, go into its properties, then into the Driver tab and click on the “Delete” button. After that, install new software downloaded from the official site of the manufacturer.

Reason 1. Cables, extension cords and hubs

The low quality of cheap USB cables, adapters and branches (they are also “hubs”) are the most common source of various problems in devices connected through a universal tire. Therefore, when an error appears, “USB device is not recognized”, the first thing to try to do is exclude the intermediate link in the video extension or hub video. That is, a flash drive, a 3G/4G model and the like we connect directly to a USB port on a computer motherboard. The front connectors on the system of the system unit are also not suitable because they are also often the cause of the malfunction, which means they should not “trust” them.

In the case of a printer or scanner. pay attention to the integrity of the cable. If there are visible damage. use another cable. It costs inexpensively and this will not protrude your budget at all.

Reason 2. Failed USB port

The second very common cause of problems with the operation of external devices is physical damage or even a breakdown of a USB port. Paradox, but often people who wash two three times a day do not follow the cleanliness of the equipment with which they communicate every day. System blocks are especially affected by this. They are often loved to “push” into the most dusty and dirty corner. As a result, dust is stuffed into all possible places, including USB ports. I even happened to discover there mummies of various bugs and insects. And the contamination of contacts also does not contribute to the stable operation of the connector. In addition, there were times when users stuck a mouse, printer or flash drive so zealously that they simply broke the port.

Therefore, when an error appears, “one of the devices connected to this computer works incorrectly”, carefully inspect the connectors for contact contamination or damage. Try to switch to neighboring and see if there are errors on it. In addition, it is worth opening the device manager and look at USB controllers-is there any of them red cross. This usually suggests that he failed and the motherboard is required to repair. Sometimes, however, the installation of an additional controller in the PCI slot saves the installation.

Printing Service and System failures

Perhaps the computer does not see the device, because it is disconnected in the press service, while the device will not be determined by the computer. Go to the control panel. administration. services. In the list you need to find the “Print Service” and check the type of launch, there should be two marks: the condition works, the type of launch is automatic.

System failure is an abstract concept, the so.called all the errors of the operating system that is difficult to explain. The reason for the failure can be elementary. a sharp shutdown of PC from the network or different programs. Perhaps before this, various software was updated, after which Windows system files were injured. The solution to this problem is the reboot of the computer, but it helps only at the initial stage.

A failure in the printer’s work occurs quite rarely and regardless of the brand. HP, Epson, Canon, etc.D. Perhaps this is affected by indirect reasons that are inconspicuous at first glance.

Viruses and antivirus

Antivirus programs can affect the installation of additional equipment, including printers. While using the program, the computer simply does not see the installed equipment. Temporarily suspend PC protection and test the printer operation.

Cleaning the operating system from viruses. a very useful event. Not all malicious in is safe, there are very unpleasant programs that can cause almost mechanical damage to the computer. It is recommended to use only licensed programs to verify PC.

Do not forget that you need to clean not only the system, but also all external discs and flash cards.

The laptop does not see the printer via USB

Many have bought a printer for a very long time, and you can only connect it with a wired way. Therefore, the first thing you should check the cables and only then move on to the setting of the printer or the operating system. If your printer is connected in another way, then this step can be skipped.

First of all, check how tightly the cable sits in both nests (on the motherboard and in the printer itself). Of course, if you have several suitable wires, then try them all. It is better to inspect them for damage, cliffs, cuts, excesses and so on. By the way, you need to connect the cable directly to the motherboard. It is better not to use USB ports on the front side of the case and not resort to the help of various USB hubs and extensions.

Also check the version of the USB. The most popular options are 2.0 and 3.0. The first has a black color, and the second is blue. It is better to connect old equipment to an earlier audit connector. Especially if you use the old operating system and old iron. It is also desirable to use the cable that came with the printer. It is with it that the device will be completely compatible. And finally, make sure you have a suitable wire. The fact is that many novice users confuse it with Ethernet with a connector due to the fact that they are visually very similar. But do not try to put a cable in the printer to connect the computer to the router, and then ask the question: “Why does the laptop not see the printer through the cord?””

The laptop does not recognize the printer through Wi-Fi

If you use a wireless connection, then most likely a program problem. Very rarely, but it still happens that an integrated Wi-Fi module in the printer is out of order. Diagnosing such a malfunction is quite difficult at home. And start checking the module only if other methods have not helped.

Installation of drivers

For the correct functioning of many devices connected to a computer, drivers are required. This is a special software with which the operating system gets access to the equipment of the equipment (in this case, the printer). Sometimes it happens that the drivers work correctly, and then, as a result of a system failure, they cease to function. over, Windows may not notify the user about the problem. Anyway, herself may not be aware of what is happening.

Problems with the driver of the Canon printer

The driver is a “capricious” thing. Constantly “flies”, breaks, damages, and t.D. And for various reasons, including “in itself broke”. In any case, the most effective way to eliminate problems with drivers is their complete reinstall. Of course, before this procedure you need to prepare the printer drivers. They can be downloaded from the official Canon website:

• Follow this link leading to the Canon online support center. Scroll the site page to the “Select the product”, then enter the line of the line and the Canon printer (for example, “Pixma E204”) in the text field, click on the reflected link.
• On the new page, open the “Drivers” section, select the operating system (usually determined) and the language (it may not be Russian. it does not matter), then click the “Download” button. Save the driver of the driver somewhere to the disk.

If the name of the printer is not displayed in the “Device Manager”, you can immediately install a downloaded driver. If it is displayed, but with an exclamation/interrogative sign, it is better to first remove the driver. This is done from the same application “Device Manager”:

• Click the right mouse button by the name of the Canon printer in the “Device Manager”, select the “Deleteer” item in the menu. In the window that appears, install the checkmark at the “Delete Driver Programs for this device” (if any) and click “Delete”. So it looks like an example of removing the audio card driver (everything is exactly the same with the printer).

You can also use the program for installing and updating the drivers, for example, Driverhub. She will automatically find and install a suitable driver for the printer.

Malfunctions in the printer firmware

As in the case of the driver, problems with the software built into the printer can occur for a heap of reasons, including “everything in itself has broken down”. There are two main ways to solve this problem. resetting the settings of built.in software to factory values ​​and, if it does not help, flashing the device (t.e. reinstallation of built.in software).

The problem needs to be solved by resetting parameters. For each separate line/model of Canon printers, this is done in different ways. Usually. by starting the corresponding function with the button/LCD control panel, which is located on the device.

Here are an example of resetting parameters for the Printer Canon Pixma TS9120 with a touch control panel:

And with the printer firmware is already more complicated. We will not consider the process itself, but we will tell you where to start. For reinstalling, you will need a special program and the firmware itself. Both that and another can also be downloaded from the official site. from the same page where the driver, but in the “Firmware” section. Here is a screenshot of the page for downloading the required software to the All-In-One Printer Canon I-Sensys MF4780W:

Please note that there are programs for operating systems Mac and Windows. After click on the “Download” button, a new page will open, where you will need to enter the printer serial number. you can’t continue without it. The number can be found on the sticker, talked to the device case.

And if you click on the link “Installation of the built.in software”, an additional menu will be displayed from below. In it you can go to the “Installation” section, which gives a brief instruction to update the firmware.

On some models of the All-In-One Printer Canon, supporting the network connection (usually by Wi-Fi), the update can be made from the control panel.
