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 protocols).
