NAME
       lsusb - list USB devices

SYNOPSIS
       lsusb [ options ]

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


OPTIONS
       -v, --verbose
              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. Can be used with the t option.

       -s [[bus]:][devnum]
              Show only devices in specified bus and/or devnum.  Both ID's are
              given in decimal and may be omitted.

       -d [vendor]:[product]
              Show only devices with the specified vendor and product ID.  Both
              ID's are given in hexadecimal.

       -D device
              Do not scan the /dev/bus/usb directory, instead display only
              information about the device whose device file is given.  The
              device file should be something like /dev/bus/usb/001/001.  This
              option displays detailed information like the v option; you must
              be root to do this.

       -t     Tells lsusb to dump the physical USB device hierarchy as a tree.
              Verbosity can be increased twice with v option.

       -V, --version
              Print version information on standard output, then exit
              successfully.


RETURN VALUE
       If the specified device is not found, a non-zero exit code is returned.


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