NAME
       lsusb - list all USB devices

SYNOPSIS
       lsusb [options]

DESCRIPTION
       lsusb is a utility for displaying information about all USB buses in the system and all devices connected to them.

       To make use of all the features of this program, you need to have Linux kernel 2.3.15 or newer which supports the /proc/bus/usb interface.

OPTIONS
       -v     Tells lsusb to be verbose and display detailed information about all devices.

       -vv    Tells lsusb to be very verbose and display even more information (actually everything the PCI device is able to tell).

       -s [[<bus>]:][<devnum>]]
	      Show only devices in specified bus and devnum.

       -d [<vendor>]:[<product>]
	      Show only devices with specified vendor and product ID. Both ID's are given in hexadecimal and may be omitted.

       -p <procpath>
	      Use another path instead of /proc/bus/usb.

       -D <device>
	      Do not scan the /proc/bus/usb directory, instead display only information if the device whose device file is given.

       -t     Tells lsusb to dump the physical USB device hierarchy as a tree.

FILES
       /usr/share/hwdata/usb.ids
	      A list of all known USB ID's (vendors, products, classes, subclasses and protocols).

       /proc/bus/usb
	      An  interface  to USB devices provided by the post-2.3.15 Linux kernels. Contains per-bus subdirectories with per-device files and a
	      devices file containing a list of all USB devices.
