NAME         top

       usb-devices - print USB device details

SYNOPSIS         top


DESCRIPTION         top

       usb-devices is a 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         top

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

FILES         top

              The part of the sysfs tree the script walks through to
              assemble the printed information.

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

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