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 successfully.


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, subclasses and protocols).
