How do you display USB device information on a Linux system?

• A. usbinfo
• B. lsusb
• C. usbdevices
• D. device -list usb

Answer: (B)

To display USB device information on a Linux system, the command `lsusb` is the correct choice. This command is specifically designed to list all USB devices currently connected to the system, providing valuable details such as the device ID, vendor ID, and product ID. When executed, `lsusb` scans the USB buses of the system and outputs a summary of the connected devices in a straightforward format. This makes it a tool of choice for users who need to troubleshoot USB connections or verify that devices are recognized by the system. Other choices, like `usbinfo`, `usbdevices`, and `device -list usb`, do not exist as standard commands in most Linux distributions. Therefore, they wouldn't be able to provide USB device information effectively. This reinforces why `lsusb` is the appropriate command in this context.
