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 de-
vices connected to them. It uses udev's hardware database to associate a full human-read-
able 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 de-
scriptors will be shown, when available, for USB device classes including hub, au-
dio, 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 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 is returned.
