NAME
       usb-devices - print USB device details

SYNOPSIS
       usb-devices

DESCRIPTION
       usb-devices  is	a (bash) shell script that can be used to display details 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/debug (if debugfs is mounted there).
       The script is primarily intended to be used if the file is not available.

       In contrast to the usb/devices file, this  script  only	lists  active  interfaces  (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  infor-
	      mation.

       /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.
