The lsusb command is used to display information about devices that are connected to the system’s USB buses. This command scans the /dev/bus/usb/ directory for information. By default, the command will print the number of the bus and the connected device, the ID of the device, and the name of the vendor and product matching that device.
You can use the -v flag to see detailed information about each device, similar to using the udevadm info command. You can also filter results by bus (-s) and by vendor/product (-d).
