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
