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.
