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

       /usr/local/share/usbutils/usb.ids
              A list of all known USB ID's (vendors, products, classes,
              subclasses and protocols).


SEE ALSO

       lspci(8), usbview(8).
