       lsusb - list all USB devices

       lsusb [options]

       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.

       -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 every-
	      thing 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.

	      A list of all known USB ID's (vendors, products,	classes,  subclasses  and  proto-

	      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.
