▷ Linux does not recognize USB. What do I do? Solution 🥇

One of the problems we face when our team is a few years old is: Linux does not recognize USB.

Linux does not recognize USB.

The first thing we have to do is test if the problem is with the USB connector of the computer, for this we will need a USB key.

What we are going to do to check if the problem is in the USB connection port is to connect the USB key in the port that we saw that Linux did not detect. We will see if it is recognized or not by the system. If Linux still does not recognize it, we can try to connect the USB memory to other USB ports on our computer.

What if no port detects it?

If we want to do more tests before taking the equipment to the technician, we can open a terminal and write there:


The terminal will show us a list with the enabled ports. The next step is to connect the USB drive to the USB port and write again


We will receive a new list with the recognized ports. We need to see if the USB we connected appears there.

If we still have hope that there is no fault in the connector of our equipment, we can try to restart the equipment. Sometimes certain processes, including the process that controls auto-sleep, can cause some sort of hang in recognizing the USB port.

Use program “disks”

The last chance to see if the flash drive is recognized or not is to use the “Disks” program. We connect a USB flash drive and then start “Disks”. If it recognizes it, we will see that it appears in the list of detected devices.

It may be the connector on your computer…

If it does not recognize USB keys, the problem is definitely the USB connector of the equipment. The most obvious solution is to bring the equipment to the technical service to change it.
