NAME

       lsusb - list all USB devices

SYNOPSIS

       lsusb [options]

DESCRIPTION

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

       To make use of all the features of this program, you need to have Linux kernel 2.3.15 or newer which supports the /proc/bus/usb interface.

OPTIONS

       -v     Tells lsusb to be verbose and display detailed information about all devices.

       -vv    Tells lsusb to be very verbose and display even more information (actually everything the PCI device is able to tell).

       -s [[<bus>]:][<devnum>]]
	      Show only devices in specified bus and devnum.

       -d [<vendor>]:[<product>]
	      Show only devices with specified vendor and product ID. Both ID's are given in hexadecimal and may be omitted.

       -p <procpath>
	      Use another path instead of /proc/bus/usb.

       -D <device>
	      Do not scan the /proc/bus/usb directory, instead display only information if the device whose device file is given.

       -t     Tells lsusb to dump the physical USB device hierarchy as a tree.

FILES

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

       /proc/bus/usb
	      An  interface  to USB devices provided by the post-2.3.15 Linux kernels. Contains per-bus subdirectories with per-device files and a
	      devices file containing a list of all USB devices.

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.

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, communi-
	      cations, and chipcard.

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

       -d [vendor]:[product]
	      Show only devices with the specified vendor and product ID.  Both ID's 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     Tells lsusb to dump the physical USB device hierarchy as a tree. This overrides 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.

FILES

       /var/lib/usbutils/usb.ids
	      A list of all known USB ID's (vendors, products, classes, subclasses and protocols).
