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.
