USB devices generally work under the plug & play mechanism. This means that, as soon as we connect them to this port on our computer, a message appears that alerts them about their synchronization. Incredible as it may seem, and as time goes by, the problems of USB not detected they keep repeating themselves. If you are going through it and you have a computer with Windows 10, we are going to offer you some possible solutions. It is a series of several simple tricks that will leave your USB working.

USB not detected: tips to solve it

The first thing you have to take into account is that we call USB that is not detected, the one that does not notify us of its presence, and that does not appear when we search for it, browsing, inside our PC.

To be sure of suffering this inconvenience, you must go to the Team, and check that it does not appear there.

If you continue without seeing it, some of the following suggestions could be useful:

Check the hardware

Maybe one of the ports of your computer fails. First of all, you have to remove that option:

Change the port where you have connected the undetected USB to another. If you are using a USB hub, remove it and make the connection directly. Connect another USB device to the same ports and verify that they do recognize them. Connect the unit USB to a different system.

Although this first tutorial does not work, it will give you the certainty that there is something wrong.

Check the file system

In Windows 10, these kinds of errors can be related to USB drive errors. These should be formatted in NFTS or exFAT to be accessible. Some FAT32s give problems. So, you have to proceed like this:

On the Start screen, press Win + R to open the run box. On Run, type “diskmgmt.msc” and click Enter. Right-click on Disk Management, then Properties. Go to the General tab and then System. Files

There you can change the formatting of your USB disk, although first make sure you have a backup just in case.

Assign a letter to the USB disk

Occasionally, a disk drive is not accessible simply because it has no letter assigned. If you want to add one, you must follow this process:

On the Start screen, press Win + R to open the run box. On Run, type “diskmgmt.msc” and press Enter. Right-click on the drive in question and select Change drive letter and path. Go to Change Assign a letter. that the equipment has not already been used for your disks Save the changes and reconnect it

Verify that the USB port is not disabled

Not everyone knows this, but sometimes repairing an undetected USB is as simple as enabling ports. Indeed, USB ports can be disabled, but also re-enabled, like so:

Open Device Manager Find universal drivers Right-click each device and select the Activate option For the changes to take effect, you have to restart your Windows 10 system

Try from Command Prompt

Right now, USB drives are also widely used to install operating systems or boot tools. Long gone are the days of CDs and DVDs. And that can suppose that Windows blocks them:

Open Command Prompt Type diskpart and hit Enter A new Command Prompt window will open. In it run List DiskIf the undetected USB disk is in the list, but it does not appear in File Explorer, it happens that Windows 10 considers its contents to be dangerous

Enabling from BIOS

Although as we have seen, it is possible to enable a USB port from Windows -or disable it-, if it had been disabled from the BIOS, we will have to go back to it to fix it:

Restart your computer and enter the BIOS by pressing F2. Inside the BIOS, go to Settings or Hardware. Select the USB ports of your device, and activate them all. Restart the machine and try connecting the unit.

Unrecognized USB device

When you go to connect a USB to your computer, always try to do it with the sound on. This, because sometimes the sound of the new connected hardware is heard, while a message on the screen indicates that it is not recognized. If this happens to you, there is an output:

Unplug the undetected USB and plug it back in firmly. If everything continues the same, open File Explorer and go to This PC. Right-click on the drive and select Format from the context menu. Go to Start, and you’re done. forward a formatting of the disk.

Locked or encrypted drives

If none of the above worked for you, there are still a couple of reasonable, but not pleasant, explanations. Everything indicates that the undetected USB disk has suffered some kind of damage, probably due to the installation of some malicious software. If you just purchased it, you should get in touch as soon as possible with where you bought it. There is a probability that the drive has been locked or encrypted. It is a normal procedure when you save sensitive personal information, and you may not remember it.


As you may have observed, there are several possible alternatives to recover an undetected USB in Windows 10. These devices are not usually easily damaged, but there are no missing drives that have been mistreated or blocked.
