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,  sub-
              classes 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.
