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.
