NAME
       usb-devices - print USB device details

SYNOPSIS
       usb-devices

DESCRIPTION
       usb-devices  is	a  (bash) shell	script that can	be used	to display de-
       tails of	USB buses in the system	and the	devices	connected to them.

       The output of the script	is similar to the usb/devices  file  available
       either  under /proc/bus (if usbfs is mounted), or under /sys/kernel/de-
       bug (if debugfs is mounted there). The script is	primairily intended to
       be used if the file is not available.

       In  contrast to the usb/devices file, this script only lists active in-
       terfaces	(those marked with a "*" in the	usb/devices  file)  and	 their
       endpoints.

       Be  advised  that  there	 can  be differences in	the way	information is
       sorted, as well as in the format	of the output.

RETURN VALUE
       If sysfs	is not mounted,	a non-zero exit	code is	returned.

FILES
       /sys/bus/usb/devices/usb*
	      The part of the sysfs tree the script walks through to  assemble
	      the printed information.

       /proc/bus/usb/devices
	      Location	where  the  usb/devices	file can normally be found for
	      Linux kernels before 2.6.31, if usbfs is mounted.

       /sys/kernel/debug/usb/devices
	      Location where the usb/devices file can normally	be  found  for
	      Linux kernel 2.6.31 and later, if	debugfs	is mounted.
