lsusb

lsusb is a command line tool used in Unix-like operating systems to list USB devices connected to the system. It stands for "list USB". When executed, it provides information about the USB devices connected to the computer, including their vendor ID (VID), product ID (PID), device speed, and description.

The output of lsusb includes details such as the bus number, device number, and device class. It also provides information about the USB controllers and hubs present on the system. Additionally, lsusb can display details like device interface associations and manufacturer names.

Users can gather specific information about a particular device by providing additional options. For instance, lsusb -v offers verbose output, giving a more detailed description of each USB device, including the supported USB version, number of configurations, and various endpoints.

lsusb is a handy tool for diagnosing USB connectivity issues, identifying connected devices, and checking if the system recognizes a specific USB device. It is frequently used by system administrators, developers, and individuals troubleshooting USB-related problems.
