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).
