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. It uses udev's hardware database to  associate  a  full  human-
       readable name to the vendor ID and the product ID.

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 IDs are  given  in  decimal
              and may be omitted.

       -d [vendor]:[product]
              Show  only devices with the specified vendor and product ID.  Both IDs 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, --tree
              Tells  lsusb  to dump the physical USB device hierarchy as a tree. Verbosity can be
              increased twice with the -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.
