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 cur‐
              rent 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).

SEE ALSO
       lspci(8), usbview(8).
