NAME
       usb-devices - print USB device details

SYNOPSIS
       usb-devices

DESCRIPTION
       usb-devices  is	a  shell  script that can be used to display details of USB buses in the system and the devices con‐
       nected 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/de‐
       vices 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.
