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. It uses udev's hardware data-
base 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 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. 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 in-
formation about the device whose device file is given. The de-
vice 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 success-
fully.
RETURN VALUE
If the specified device is not found, a non-zero exit code is returned.
