lsusb(8)               (11 February 2019)                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. It
          uses udev's hardware database to associate a full human-
          readable name to the vendor ID and the product ID.

     OPTIONS
          -v, --verbose
               Tells lsusb to be verbose and display detailed informa-
               tion about the devices shown.  This includes configura-
               tion descriptors for the device's current speed.  Class
               descriptors will be shown, when available, for USB
               device classes including hub, audio, HID, communica-
               tions, and chipcard. Can be used with the t option.

          -s [[bus]:][devnum]
               Show only devices in specified bus and/or devnum. Both
               IDs are given in decimal and may be omitted.

          -d [vendor]:[product]
               Show only devices with the specified vendor and product
               ID.  Both IDs 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, --tree
               Tells lsusb to dump the physical USB device hierarchy
               as a tree. Verbosity can be increased twice with 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
