In the device manager there is a notification: “This device is not currently connected to the computer” - code 45 appears next to it? A similar picture was noticed when disconnecting or connecting equipment. The user himself can do this, however, failure of a particular hardware cannot be ruled out.
In fact, a similar message may appear when connecting any equipment. Particularly affected are phones that are somehow connected to a PC - charging in progress, but the device itself is not detected. The failure is also common when working with:
You may also receive alerts when someone tries to connect from a computer we don't recognize. To enable or manage two-factor authentication. Receive codes via text message on your mobile phone, receive security codes using a code generator, press the security key on a compatible device, receive security codes from third party application, approve a connection attempt using a device that we recognize, use any of your printable recovery codes. If you haven't registered the computer or mobile device you're using, you'll be prompted to do so when you turn on two-factor authentication. This way, you won't need to enter a security code for future connections. Do not click the "Save this Browser" button if you are using a public computer that others may be using.

Error Code 45 - Device not connected
Solving the problem
Obviously, the problem arose with hardware that is no longer detectable - you can simply deactivate it and delete the device through the manager. Conversely, if the alert appears when disconnected, then simply connect it and the fault icon will stop appearing.
The code generator works on your mobile device, even if you don't have access to text messages or Internet connection. You can also use it if you need to reset your password. Set up a code generator. On this moment you can only set up the code generator from your computer. To set up a code generator.
Go to the "Use two-factor authentication" section and click "Edit".
- Go to Code Generator and click Setup.
- Follow the instructions on the screen.
In theory, this message is not an error, but only indicates the need to reconnect the device.
Now open the device manager by right-clicking on the “Computer” icon, selecting "Properties" And "Device Manager". If there is a yellow icon with a question next to the problematic device, this means that the device is not recognized, and if there is a red exclamation mark, then an error occurs during its operation. In this case, the procedure is as follows.
These alerts tell you what device was trying to connect and its location. To receive notifications about unrecognized connections. As soon as you start receiving alerts about unrecognized connections.

Connected objects are becoming more and more present in our lives, and this is just the beginning. It was a long time ago when our computer networks consisted only of computers, printers or servers.
Saving error is fixed Removing a device And cleaning its drivers. After reconnecting, try to reinstall latest version drivers.
If during installation driver package For of this equipment errors occur or the information still shows code 45, then we remove the device again, update the drivers for the motherboard and network card and other important components.
Now the boxes and related objects monopolize the network of each home. This could be its original configuration or thus the ability to integrate it into another system using sound, for example. The first reflex might be to scan your window's interface to see if you can find the device. But if you have a lot, it can quickly become tedious. Here are some solutions for this.
It's small software can only find manufacturer's devices. Of course, the computer you are using must be on the same network as the device you are looking for. If the manufacturer does not provide a specific tool, you can use a network scanner. This will allow you to connect all devices connected to the network, you will need to filter by "Provider". And there is a difficulty because this is the name of the network chipset manufacturer, not the name of the device.
In such a situation, there may be a physical defect in the interface or an incorrect connection of the equipment. Failure of components cannot be ruled out: USB port, motherboards, audio cards or GPUs, RAM and others. We advise you to make sure that they are in good working order.
The error itself appeared en masse recently, which may also indicate bugs in Windows build(relevant for dozens) - if you applied a build update, then I recommend rolling back the OS and trying connecting the device again.

Damage to the computer USB port
It is impossible to repair the port without the help of a specialist, but you can check it simply. If the computer does not recognize the smartphone, then you need to connect through another USB port. If it helps, it means the cause has been found, if not, let’s move on.
System problems in the phone
Sometimes the problem of lack of connection can be solved very simply: by turning off the smartphone, removing the battery from it for a few seconds, returning it to its place and turning on the device. Simple and effective.
Let's see how it really is. This hardware chip uses a 7-bit address, so it can manage up to 128 addresses. Since the controller has a fixed address assigned to device 0 for device initialization, 127 devices can be physically connected. The controller mainly differentiates between hubs and devices. Hubs are actually like splitters that can be connected to other hubs or end devices. Each end device has at least one function, and each function is assigned one address.
Phone jack failure
If the phone has been damaged by water, or its connector has been mechanically damaged, then this may be the problem. Alas, if cleaning the socket does not give any results, then only replacing the damaged part will help.
Incorrect connection settings
In the device settings, you need to find the menu for USB connection to a computer. In many Samsung models, it is located at “Memory” > “Properties”. If by default the checkbox is next to USB usage as a modem - remove it, find the “Media device” item and activate it.
On the other hand, for example, a multifunction device can use multiple addresses at the same time, since the controller is perceived as a hub to which other end devices are connected. For example, a multifunction printer, scanner, and fax machine have four addresses. To connect multiple end devices to your computer, you need to use multiple hubs, which also occupy one behind the other. In addition to the limit set by the number of free addresses, we must also consider power limitations.
Driver problems
They are solved by installing drivers from the “native” disk, or downloading them from the manufacturer’s official website.
Also, the problem may be that power is turned off on some ports on the computer. You can check this by going to the “Control Panel”, finding the item “Hardware and Sound”> “Power Options”> “Power”. Next, open the appropriate settings and click on change additional parameters. In the menu that opens, open the USB options, and then the options for temporarily disabling the USB port. Change its value to “Prohibited” and activate it with the “Apply” button.
Each individual hub must be powered separately because 127 devices will not be able to power continuous four-port hubs at the same time. Any other connected drive will not show up in your Disk Manager. But you need to connect it through hubs, which also need to be eliminated so that you can't connect to 127 end devices in practice.
However, five hubs can be connected to each other. A refrigerator that connects to the Internet and searches for recipes? Is it possible to find out through your mobile phone how it is set on your home thermostat? If you're a fan of new technology, being able to connect your whole family to the Internet will make your life easier.
Problems with device drivers
In the “Device Manager”, the “Portable devices” item should be without any warning signs. You should also check the functionality of the device through “Properties”. If it is not there, then you need to reinstall the corresponding driver.
Another solution would be to update your smartphone drivers. On the Samsung Galaxy A5, as well as on other models of the brand, this can be done using the Samsung Kies software.
From smart mobile phones to smart refrigerator
The concepts of "smart home" or "smart home" have been very common in recent times. If you can make a lot of things easier to take care of your home and household, it would be a mistake to avoid such a decision. The possibilities for home automation and remote control are becoming increasingly widespread. Usually it is enough to manage mobile device in the form of a smartphone or tablet.
Do you want to live in a smart home and control your functions via the Internet? If you decide to have a home or apartment solution online before entering the project, all changes can be built in. The solution will be as comprehensive as possible. When renovating an old building, you will need to replace the wiring to solve the bus, which is not very cheap. But your investment will return to you in the form of greater comfort and energy savings.
Android OS malfunction or viruses
In this case, cleaning the phone with an antivirus, resetting the settings to factory settings, or completely reflashing it can help.
As you can see, there can be a lot of options for why the connected Samsung phone is not located on the computer, so to find a solution you need to be patient. We hope everything works out for you!
Sockets that know a lot of things
One of the favorite solutions for home appliances is remote controlled electrical outlets that you can control many activities. You will have to do this manually. A switch element connected between the wall socket and the electrical appliance is sufficient. Purchasing a basic set of these remote control switches can cost hundreds of hundreds of dollars, and at correct connection they can be controlled via the Internet.
A remote-controlled heater or heating system guides you to the desired temperature over time. Similarly, you can regulate the temperature in distant objects - for example, in a country house. Remote control ventilation and air conditioning, turning on and off all household appliances from washing machine to the cleaning robot. Although this does not appear to be the case, automation with appropriate settings and the ability to manually enter actions is a great help. Once you get used to a system like this, it's hard to imagine having to figure everything out at home.
