Man Page of lsusb

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.

       -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.
              This overrides the v option.

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


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


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