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/ker-
       nel/debug (if debugfs is mounted there). The script is primairily 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.
