SYNOPSIS

DESCRIPTION

12       lsusb  is  a  utility for displaying information about USB buses in the
13       system and the devices connected to them.

OPTIONS

17       -v, --verbose
18              Tells lsusb to be verbose and display detailed information about
19              the  devices shown.  This includes configuration descriptors for
20              the device's current speed.  Class descriptors  will  be  shown,
21              when  available,  for  USB  device classes including hub, audio,
22              HID, communications, and chipcard.
23
24       -s [[bus]:][devnum]
25              Show only devices in specified bus and/or devnum.  Both ID's are
26              given in decimal and may be omitted.
27
28       -d [vendor]:[product]
29              Show  only  devices  with  the  specified vendor and product ID.
30              Both ID's are given in hexadecimal.
31
32       -D device
33              Do not scan the /dev/bus/usb  directory,  instead  display  only
34              information  about  the  device whose device file is given.  The
35              device file should be something like /dev/bus/usb/001/001.  This
36              option displays detailed information like the v option; you must
37              be root to do this.
38
39       -t     Tells lsusb to dump the physical USB device hierarchy as a tree.
40              This overrides the v option.
41
42       -V, --version
43              Print   version  information  on standard output, then exit suc‐
44              cessfully.

RETURN VALUE

48       If the specified device is not found, a non-zero exit code is returned.

FILES

52       /usr/share/hwdata/usb.ids
53              A list of all known USB ID's (vendors, products,  classes,  sub‐
54              classes and protocols).
