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 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.
