lsusb

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.

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

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

SEE ALSO

       lspci(8), usbview(8).
