Why does not see USB?
There are many reasons why a PC does not want to recognize a USB flash drive and work with it. We list the options that occur most often.
Causes of USB problems
Cybernetic pests can disable both the individual elements of the computer structure (the same USB) and the whole PC system in general. So, in order to avoid this problem or eliminate an existing one, scan the system with an antivirus (just choose the good one from the paid versions) and remove the detected parasites. By the way, do not forget to regularly scan and devices that you connect to your PC (phone, USB flash drive, MP3 player, external hard drive, etc.) - the information that they contain can easily creep into a virus.
If everything is already too trivial or if the virus is extremely ingenious, then you can bring your PC back to life by reinstalling the operating system.
Problems with a flash drive
A flash drive is a device quite fragile, and therefore it can easily be damaged when dropped. In addition, the gadget may burn out or turn out to be simply of poor quality (in this case, you need to contact the seller with the requirement to return the money or replace the product).Finally, each flash drive has a life assigned to it by the factory. An old device may simply become unusable. In this case, will only purchase a new product.
They are required for the USB ports to work on the computer. These utilities can be installed “crookedly” during the installation or, after some time, “fly off” for one reason or another. Of course, this does not happen very often, but if a problem does arise, simply update the appropriate software.
To do this, go to the “Computer” folder, right-click on any area of the clean folder space, and then select “Properties”. In the window that opens, in the list on the left, select “Device Manager” and then “USB Controllers”. To expand the list, click on the plus sign next to these words. Now insert your USB flash drive or any other device that you want to connect to your PC via USB port. Watch the list - one of the positions may change or a new one may be added. You will need to click on it with the same right mouse button and select "Delete". We have removed from the system the old, dilapidated driver.Now remove the device and reinsert it - the driver will automatically update. If the PC does not see the device after this, then the problem may lie in the reason we described below.
File System Conflict
If the NTFS file system is on the PC and FAT is on the flash media, then a “misunderstanding” may occur between the devices. The computer may simply not recognize the device it does not like.
This problem can be eliminated by formatting the flash drive in the PC file system. This can be done with the help of special programs that allow you to see the device even when the PC itself does not accept it. Alternatively, it may be a utility called HP USB Disk Storage Format Tool. But first go to "My Computer" and right-click on the "Disk D". Select Properties, General. From there you will find out which file system is installed on your computer.
USB port issue
This is also a common reason why your precious PC does not see USB. If, when assembling a computer, negligent technicians forgot to fasten the front panel of the system unit to the motherboard, then a USB flash drive or any other device (for example, a phone) connecting via the connector located on this front panel will not be recognized.In addition, the headphones connected to the audio output jack in the front of the system unit will not work either.
With this problem, you will need to contact the service center of the store where you bought the PC.
Also, the USB port may burn out. This often happens in desktops and laptops. The problem may occur for various reasons. For example, due to a sharp voltage drop or inaccurate handling of the port. This item can be replaced with a new one.
