Linux usb device listing

4 Useful Way to Know Plugged USB Device Name in Linux

As a newbie, one of the many things you should master in Linux is identification of devices attached to your system. It may be your computer’s hard disk, an external hard drive or removable media such USB drive or SD Memory card.

Using USB drives for file transfer is so common today, and for those (new Linux users) who prefer to use the command line, learning the different ways to identify a USB device name is very important, when you need to format it.

Once you attach a device to your system such as a USB, especially on a desktop, it is automatically mounted to a given directory, normally under /media/username/device-label and you can then access the files in it from that directory. However, this is not the case with a server where you have to manually mount a device and specify its mount point.

Linux identifies devices using special device files stored in /dev directory. Some of the files you will find in this directory include /dev/sda or /dev/hda which represents your first master drive, each partition will be represented by a number such as /dev/sda1 or /dev/hda1 for the first partition and so on.

List All Linux Device Names

Now let’s find out device names using some different command-line tools as shown:

Find Out Plugged USB Device Name Using df Command

To view each device attached to your system as well as its mount point, you can use the df command (checks Linux disk space utilization) as shown in the image below:

Find USB Device Name Using df Command

Use lsblk Command to Find USB Device Name

You can also use the lsblk command (list block devices) which lists all block devices attached to your system like so:

List Linux Block Devices

Identify USB Device Name with fdisk Utility

fdisk is a powerful utility which prints out the partition table on all your block devices, a USB drive inclusive, you can run it will root privileges as follows:

List Partition Table of Block Devices

Determine USB Device Name with dmesg Command

dmesg is an important command that prints or controls the kernel ring buffer, a data structure which stores information about the kernel’s operations.

Run the command below to view kernel operation messages which will as well print information about your USB device:

dmesg – Prints USB Device Name

That is all for now, in this article, we have covered different approaches of how to find out a USB device name from the command line. You can also share with us any other methods for the same purpose or perhaps offer us your thoughts about the article via the response section below.

How to List USB Devices in Linux

Nowadays, many computer peripherals such as webcams, mice, scanners, printers, hard drives, USB (Pendrive) now come as USB devices. Once these devices are connected to the Desktop or server it’s important to know the device name or device path. This helps to identify USB devices for the tasks such as formatting.

In Linux, all device files are stored in /dev directory and must be available to the OS during the system boot.

In this guide, we will show you the various ways to list USB devices on Linux. Most commands mentioned here should work on all Linux distributions.

List USB Device Names Using df Command

The df command is a useful command that can help list all mounted volumes, including your USB drives.

Once a USB device is plugged into a Linux system, especially for Desktop, it is automatically mounted in the /media partition and becomes ready for use.

From the output above, I have 1 USB drive /dev/sdb with 2 partitions /dev/sdb1 and /dev/sdb2

List USB Device Name using lsblk Command

Lsblk command is used to list all block devices on a Linux system. From the list, you can filter USB devices using the grep command.

To retrieve additional information such as the UUID, manufacturer and filesystem type, use the blkid command as shown.

List USB Device Names Using fdisk Command

You can use the good old fdisk command that is used for partitioning volumes to list all the partitions on the Linux system, including the USB drives.

The command will display detailed information about your USB volume including the partitions, size of the volume, sectors, and the filesystem type.

List USB Devices Details using lsusb Command

The lsusb command, also known as the “List USB” command, is used in Linux to list all the USB devices attached to the system.

The output above displays the Bus ID, Device ID, USB ID, and the vendor or manufacturer of the USB devices

The lsusb command simply lists the connected devices and does not provide further information about the usb devices.

For more information about the attached USB devices use the dmesg command. The dmesg command also known as “driver message” or “display the message” is used for examining the boot messages. Additionally, it is used for debugging hardware-related issues and printing messages generated by device drivers.

You can use the dmesg command and grep to narrow down to USB devices.

Also, you can pipe the output of dmesg command to less for easier scrolling.

On the output, you can search for a specific string by pressing the forward slash key ( / ) on your keyboard followed by the name or Device ID of the USB device.

In my case, I’m searching for more information regarding a USB device called SanDisk, which is actually my removable pen drive.

List USB controllers and devices using usb-devices

The usb-devices command is a shell script that allows you to list all the USB controllers and the USB devices connected to your PC. It prints out details of the USB device such as the manufacturer, product name, serial number, and so much more. Here’s the output of the command:


In this guide, we have demonstrated different ways to list the USB devices attached to the Linux system.

How to List USB Devices Connected to Your Linux System

How do you list the USB devices in Linux?

The question can have two meanings.

  • How many USB ports are (detected) on your system?
  • How many USB devices/disks are mounted (plugged in) to the system?

Mostly, people are interested in knowing what USB devices are connected to the system. This may help troubleshoot the USB devices.

The most reliable way is to use this command:

It shows the webcam, Bluetooth, and Ethernet ports along with the USB ports and mounted USB drives.

But understanding the output of lsusb is not easy and you may not need to complicate things when you just want to see and access the mounted USB drives.

I will show you various tools and commands you can use to list USB devices connected to your system.

I have connected a 2GB pen-drive, 1TB external HDD, Android smartphone via MTP and USB mouse in the examples unless stated otherwise.

Let me start with the simplest of the options for desktop users.

Check connected USB devices graphically

Your distribution file manager can be used to view USB storage devices connected to your computer. As you can see in the screenshot of Nautilus (GNOME File Manager) below.

The connected devices are shown in the sidebar (Only USB Storage devices are shown here).

You can also use GUI applications like GNOME Disks or Gparted to view, format, and partition the USB Storage devices connected to your computer. GNOME Disks is preinstalled in most distributions using GNOME Desktop Environment by default.

This app also works as a very good partition manager too.

Enough of the Graphical tools. Let us discuss the commands you can use for listing the USB devices.

Using the mount command to list the mounted USB devices

The mount command is used for mounting partitions in Linux. You can also list USB storage devices using the same command.

Generally, USB storage is mounted in the media directory. Thus, filtering the output of mount command on media will give you the desired result.

Using df command

df command is a standard UNIX command used to know the amount of available disk space. You can also use this command to list USB storage devices connected using the command below.

Using lsblk command

The lsblk command is used to list block devices in the terminal. So, here also by filtering the output containing media keyword, you can get the desired result as shown in the screenshot below.

If you are more curious, you can use the blkid command to know the UUID, Label, Block size etc.

This command gives more output as your internal drives are also listed. So, you have to take references from the above command to identify the device you wish to know about.

Using fdisk

fdisk, the good old command line partition manager, can also list the USB storage devices connected to your computer. The output of this command is also very long. So, usually, the connected devices get listed at the bottom as shown below.

Inspecting /proc/mounts

By inspecting the /proc/mounts file, you can list the USB Storage devices. As you can notice, it shows you the mount options being used by filesystem along with the mount point.

Display all the USB devices with lsusb command

And we revisit the famed lsusb command.

Linux kernel developer Greg Kroah-Hartman developed this handy usbutils utility. This provides us with two commands i.e. lsusb and usb-devices to list USB devices in Linux.

The lsusb command lists all the information about the USB bus in the system.

As you can see this command also shows the Mouse and Smartphone I have connected, unlike other commands (which are capable of listing only USB storage devices).

The second command usb-devices gives more details as compared but fails to list all devices, as shown below.

Greg has also developed a small GTK application called Usbview. This application shows you the list of all the USB devices connected to your computer.

The application is available in the official repositories of most Linux distributions. You can install usbview package using your distribution’s package manager easily.

Once installed, you can launch it from the application menu. You can select any of the listed devices to get details, as shown in the screenshot below.


Most of the methods listed are limited to USB storage devices. There are only two methods which can list other peripherals also; usbview and usbutils. I guess we have one more reason to be grateful to the Linux Kernel developer Greg for developing these handy tools.

I am aware that there are many more ways to list USB devices connected to your system. Your suggestions are welcome.

Как в Linux посмотреть подключенные USB устройства

В настоящее время многие компьютерные периферийные устройства, такие как веб-камеры, мыши, сканеры, принтеры, жесткие диски, USB (Pendrive) подключаются по USB. После того, как эти устройства подключены к рабочему столу или серверу, важно знать имя устройства или путь к нему. Это помогает идентифицировать USB устройства для таких задач, как форматирование или отключение.

В Linux все файлы устройств хранятся в каталоге /dev и должны быть доступны во время загрузки системы.

В этой статье я покажу вам различные способы как в ubuntu посмотреть usb устройства. Большинство команд, упомянутых здесь, должны работать практически на всех дистрибутивах Linux. Например Ubuntu, Debian, Mint.

Просмотр списка имен USB устройств с помощью команды df

Команда df — это полезная команда, которая может помочь составить список всех подключенных томов, включая USB-накопители.

Как только USB-устройство подключается в систему Linux, это устройство автоматически монтируется в раздел /media и становится готовым к использованию.

Из приведенного выше вывода следует, что у меня есть 1 USB-накопитель /dev/sdb с 2 разделами /dev/sdb1 и /dev/sdb2

Список имен подключенных USB — устройств с помощью команды lsblk

Команда Lsblk используется для перечисления всех блочных устройств в системе Linux. Из списка можно фильтровать USB-устройства с помощью команды grep.

Чтобы получить дополнительную информацию, такую как UUID, производитель и тип файловой системы, используйте команду blkid, как показано на рисунке ниже.

Список USB — устройств с помощью команды fdisk

Вы можете использовать старую добрую команду fdisk, которая используется для разбиения томов на разделы, чтобы перечислить все разделы в системе Linux, включая USB-накопители.

Запятая будет отображать подробную информацию о вашем USB-томе, включая разделы , размер тома, секторы и тип файловой системы.

Список сведений о подключенных USB-устройствах с помощью команды lsusb

Команда lsusb, также известная как команда “List USB”, используется в Linux для перечисления всех USB-устройств, подключенных к системе.

На выводе выше отображается идентификатор шины, идентификатор устройства, идентификатор USB, а также поставщик или производитель USB-устройств

Команда lsusb перечисляет подключенные устройства и не предоставляет дополнительной информации о USB-устройствах.

Для получения дополнительной информации о подключенных USB устройствах используйте команду dmesg. Команда dmesg, также известная как “сообщение драйвера” или “показать сообщение”, используется для проверки загрузочных сообщений. Кроме того, эта команда используется для отладки проблем, связанных с оборудованием и печати сообщений, генерируемых драйверами устройств.

Вы можете использовать команду dmesg и grep, чтобы сузиться до USB-устройств.

Кроме того, вы можете передать вывод команды dmesg в less для облегчения прокрутки.

На выходе вы можете найти определенную строку, нажав клавишу прямой косой черты ( / ) на клавиатуре, а затем имя или идентификатор устройства USB-устройства.

В моем случае я ищу дополнительную информацию о USB устройстве под названием SanDisk.

Поиск USB-накопителя

Список USB контроллеров и устройств, использующих USB устройства

Команда usb-devices-это сценарий оболочки, который позволяет вам перечислить все USB-контроллеры и USB-устройства, подключенные к вашему компьютеру. Он печатает детали USB-устройства, такие как производитель, название продукта, серийный номер и многое другое. Вот вывод команды:


В этой статье мы продемонстрировали различные способы просмотра USB-устройств, подключенных к системе Linux.
