How to Reset USB Device Using Command Line in Linux

Resetting a USB device from the Command Line Interface (CLI) can help resolve issues such as unresponsiveness or connection problems. This guide will walk you through the steps to reset a USB device using simple commands.

Step 1: Identify the USB Device in Linux

Before resetting the USB device, you must identify it by using the lsusb command, which lists all USB devices connected to your system.

You’ll see a list of connected USB devices, something like this:

Find USB Drive in Linux — Find a USB Drive in Linux

Note the bus and device number of the USB device you want to reset (e.g., Bus 001 Device 004).

Step 2: Unmount the USB Device in Linux

If the USB device is mounted, you need to unmount it before resetting it by using the umount command followed by the device’s mount point.

You can use the df command to see where the USB device is mounted:

df -h

Look for your USB device in the output, which will usually looks like /media/username/device_name.

Now run the command below, replacing /media/username/device_name with the actual mount point:

sudo umount /media/username/device_name

Step 3: Reset the USB Device in Linux

After unmounting the device, you can reset it using the usbreset utility. If you don’t have usbreset installed, you can install it using the following appropriate command for your specific Linux distribution.

sudo apt install usbutils         [On Debian, Ubuntu and Mint]
sudo yum install usbutils         [On RHEL/CentOS/Fedora and Rocky/AlmaLinux]
sudo emerge -a sys-apps/usbutils  [On Gentoo Linux]
sudo apk add usbutils             [On Alpine Linux]
sudo pacman -S usbutils           [On Arch Linux]
sudo zypper install usbutils      [On OpenSUSE]    
sudo pkg install usbutils         [On FreeBSD]

Once installed, you can reset the USB device using the following command by replacing Bus 001 Device 004 with your USB device’s bus and device number:

sudo usbreset /dev/bus/usb/001/004

Alternatively, you can use the following command, where <device_id> is the ID of the USB device (from the lsusb output):

sudo usbreset 090c:1000

Step 4: Remount the USB Device in Linux

After resetting the USB device, you can remount it. If your system does not automatically mount it, you can do it manually by running the following commands.

lsblk
sudo mount /dev/sdX1 /media/username/device_name

Replace /dev/sdX1 with your USB device’s identifier, which you can find using the lsblk command.

Finally, verify that the USB device is functioning properly by running the lsusb command. If it appears in the list, it is successfully reset and ready to use.

Conclusion

Resetting a USB device from the Linux terminal is a straightforward process that can help resolve various issues. By following the steps outlined above, you can identify, unmount, reset, and remount your USB device without much hassle.
