CompTIA Linux+ (XK0-004) — Question 153

A Linux administrator needs to take stock of USB devices attached to the system.
Which of the following commands would be BEST to complete this task?

Answer options

• A. lspci
• B. lsusb
• C. cat /proc/USB
• D. modprobe -ג€"usb

Correct answer: B

Explanation

The command 'lsusb' is specifically designed to display information about USB devices connected to the system, making it the best choice. The 'lspci' command lists PCI devices, 'cat /proc/USB' is not a valid command, and 'modprobe -g€"usb' is used to load USB kernel modules rather than list devices.
