USB devices are quite common these days. I’ve digital cam, Pen drive, external hard disk, mouse and other stuff. So how do I tell what hardware is connected via USB to my Linux desktop?
lsusb is a utility for displaying information about USB buses in the system and the devices connected to them. To make use of all the features of this program, you need to have a Linux kernel which supports the /proc/bus/usb interface.
-v command option is very informative. It tells lsusb to be verbose and display detailed information about the devices shown. This includes configuration descriptors for the deviceâ€™s current speed. Class descriptors will be shown, when available, for USB device classes including hub, audio, HID, communications, and chipcard.
