Report

The ‘lsusb’ command in Linux is a useful utility for displaying information about USB buses and the devices connected to them. It provides a detailed view of the USB hardware connected to your system, including details such as speed, bus number, device class, and type. This command is particularly valuable for troubleshooting USB devices and understanding the hardware configuration of your Linux system.

Syntax

lsusb [ options ]

Basic Example

By default, running the command without any options will list all USB devices connected to the system, showing basic information like the device ID and a brief description.

Key Options for the ‘lsusb' Command

1. -v (Verbose Mode)

This option is used to display the output in verbose mode and also display detailed information about the devices connected. 

lsusb -v

2. -s (Select Specific Device)

This option is used to display the only device specified by the bus and/or device number.

Example:

lsusb -s 2:4

3. -t (Display USB Hierarchy as a Tree)

This option is used to dump the physical USB device hierarchy as a tree.

Example:

lsusb -t

4. -D (Display Specific Device File Information)

This option is used to display information about the specified device file. The device file should be like /dev/usb/002/004.

Example:

lsusb -D /dev/bus/usb/002/004

Conclusion

The ‘lsusb’ command is a helpful tool in Linux for checking and fixing USB devices. It shows detailed information about USB buses and connected devices, helping users and system administrators understand their hardware setup. Learning how to use its different options can make it much easier to manage and solve problems with USB devices on Linux.
