lsusb(8)                               Linux USB Utilities                               lsusb(8)



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
       /var/lib/usbutils/usb.ids
              A  list  of  all  known USB ID's (vendors, products, classes, subclasses and proto‐
              cols).
