usb-devices(1)                Linux USB Utilities               usb-devices(1)

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 primarily 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.
