What should I do if the computer does not see the USB? First of all, you need to make sure that the device itself, which you need to connect, is not damaged. It can be checked very simply: if everything is normal when you connect it to another computer, then the device itself is OK. In addition, connecting it to your PC, pay attention to whether the light is on (LED). If the computer does not see the phone, the USB ports and cable can be fully functional, but you need to check the settings of the device and confirm the possibility of data exchange between it and the computer (if this option is disabled, the device will not be displayed on your computer). This also applies to tablet PCs, smartphones, MP3 players and similar gadgets.
Many people connect new devices to theUSB-ports, located on the front panel of the system unit. However, very often the front ports do not have a connection to the power supply, or there is power, but it is not enough to work correctly. What if the computer does not see the USB in this situation? It is enough simply to reconnect the device to one of the ports that are behind.
Sometimes the system immediately detects a newbut a message that the device is not recognized, and refuses to read the information. Most often the problem lies, again, in undernourishment and is solved by connecting the carrier to another port. However, in some cases, there is a need to update the drivers. It's easier and more convenient to do this with the help of specialized programs (say, Everest). It will help you learn the name of your board, and then download the appropriate driver from the official sites of the manufacturers.
Also, possibly, the malfunction has occurred because of,that Windows has assigned the already used volume label (letter) to the new device. This is corrected using the control panel tools (right-click on the "My Computer" icon, select "Management" in the menu that appears). On the right you will see the "Storage devices" tab, and in it "Disk management". It remains only to find the label of our device, press the right mouse button and select the item "Path to the disk" ("Change the drive letter"). In the window that opens, enter a new symbol. After that the problem can be eliminated.
What should I do if the computer does not see the USB? Although very rare, it still happens that the ability to read data from USB devices is disabled in the BIOS. Most often it is done in Internet salons and similar establishments, so that people, using their media, do not infect computers with viruses. If you are talking about a home PC, you should go to the BIOS, and then put a check mark that allows the motherboard to include USB devices.
If the computer does not see the USB information on theyour drive, this may be due to the presence of malicious virus programs on the PC itself or the attached device. Here the solution is obvious: you should download a reliable powerful antivirus and conduct a full scan of both the computer itself and the drive.
This advice, rather, concerns those who can notconnect the USB flash drive. What if the computer does not see the USB drive, and you have already done everything described above? You need to know that sometimes there is a conflict between the file systems of the USB devices and the PC. As a rule, on a USB flash drive, these are FAT and FAT32 systems. Modern hard drives support the NTFS system. With the help of the already known to us "Disk Management" you can change the type of the file system of the flash drive to FAT32 or NTFS.
Finally, you may need to simplyFormat the drive. This can be done if it is displayed in the list of connected devices. However, when formatting, all the data stored on it will be irretrievably deleted.
