If we take statistics on problems with a PC, then a lot of questions from users arise when connecting various devices to a computer: flash drives, external hard drives, cameras, TVs, etc. The reasons why the computer does not recognize this or that device may be a lot of…
In this article, I want to consider in more detail the reasons (which, by the way, I often came across myself) why the computer does not see the camera, as well as what to do and how to restore the operability of devices in one case or another. So, let's begin…
Connection wire and USB ports
The first and most important thing I recommend doing is checking 2 things:
1. USB cable, which you connect the camera to the computer;
2. USB port into which you insert the wire.
It is very simple to do this: you can connect, for example, a USB flash drive to the USB port – and it will immediately become clear whether it works. The wire is easy to check if you connect a phone (or other device) through it. It often happens with desktop PCs that the USB ports on the front panel are not connected, so you need to connect the camera to the USB ports on the back of the system unit.
In general, no matter how trite it may sound, until you check and make sure that both are working, there is no point in 'digging' further.
Battery / camera battery
When buying a new camera, the battery or the supplied battery is not always charged. Many, by the way, when you first turn on the camera (by inserting a discharged battery), they generally think that they bought a broken device, tk. it doesn't turn on and doesn't work. An acquaintance who works with a similar technique regularly tells me about such cases.
If the camera does not turn on (whether it is connected to a PC or not), check the battery charge. For example, Canon chargers even have special LEDs (light bulbs) – when you insert the battery and connect the device to the network, you will immediately see a red or green light (red – the battery is empty, green – the battery is ready for use).

The battery charge can also be monitored on the display of the camera itself.
Turn on / off device
If you connect a camera that is not turned on to a computer, then absolutely nothing will happen, it's all the same that you simply inserted a wire into a USB port to which nothing is connected (by the way, some models of cameras allow you to work with them when connected and without additional actions).
So, before you connect the camera to the USB port of your computer, turn it on! Sometimes, when the computer does not see it, it is useful to turn it off and on again (with a cable connected to the USB port).

As a rule, Windows after such a procedure (when a new device is connected for the first time) will inform you that it will be configured (new versions Windows 7 / 8 install drivers in most cases automatically) . You, after setting up the equipment, will also notify you Windows – you just have to start using it …
Drivers for the camera
Not always and not all versions Windows are able to automatically detect your camera model and configure drivers for it. For example, if Windows 8 automatically configures access to a new device, then Windows XP is not always able to find a driver, especially for new equipment.
If your camera is connected to a computer, and the device is not displayed in 'my computer' (as in the screenshot below) – you need to go to the device manager and see if there are any exclamation points yellow or red.
'My computer' – the camera is connected.
How do I go to Device Manager?
1) Windows XP: Start—> Control Panel—> System. Next, select the 'Hardware' section and click on the 'Device Manager' button.
2) Windows 7 / 8: press the Win + X button combination, then select Device Manager from the list.
Windows 8 – starts the 'device manager' service (the combination of Win + X buttons).
Take a close look at all the tabs in Device Manager. If you have connected a camera – it should be displayed here! By the way, it is quite possible, just with a yellow icon (or red).
Windows XP. DeviceManager: USB device not recognized, no drivers available.
How to fix driver error?
The easiest way is to use the driver disc that came with your camera. If this is not the case, you can use the website of the manufacturer of your device.

Viruses, antiviruses and file managers
Relatively recently, he himself faced an unpleasant situation: the camera sees files (photos) on the SD card – the computer, when you insert this flash card into the card reader, does not see, as if there is not a single picture on it. What to do?
As it turned out later, this is a virus that blocked the display of files in Explorer. But the files could be viewed through some file commander (I use Total Commander – official site: http://wincmd.ru/)
In addition, it also happens that the files on the SD card of the camera can be simply hidden (and in the explorer Windows such files are not displayed by default). To see hidden and system files in Total Commander:
– click in the panel above 'configuration -> settings';
– then select the section 'Contents of panels' and put a checkmark in front of the item 'Show hidden / system files' (see screenshot below).
Setting up the total commander.
Antivirus and firewall can block the connection of the camera (sometimes this happens). I recommend disabling them for the duration of testing and tuning. It is also useful to disable the built-in firewall in Windows.
To disable the firewall, go to: Control Panel \ System and Security \ Firewall Windows, there is a shutdown function, activate it.
And the last …
1) Check your computer with a third-party antivirus. For example, you can use my article on online antivirus software (you don't need to install anything): https://pcpro100.info/kak-proverit-kompyuter-na-virusyi-onlayn/
2) To copy photos from a camera that does not see the PC, you can take out the SD card and connect it through a laptop / computer card reader (if you have one). If not, the price of the issue is several hundred rubles, it resembles an ordinary USB flash drive.
That's all for today, good luck to everyone!
