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 device’s current speed. Class descriptors will be shown, when available, for USB device classes including hub, audio, HID, communications, and chipcard.
