# makedevs.sh: Script for creating nodes and links in the /dev directory,
# which are missing. Usually it will be started via the boot script and with &
# or from a script which is started via the boot script and with &.
# Existing files remain unchanged, forgotten ones will be created.
# Usefull also for a kernel without devfs support.
# See also devices.txt with the Linux allocated devices
# (/usr/src/linux/Documentation/devices.txt).
# Such scripts are often used with a busybox linux and few devices.
# Similar scripts often have the name mkdev.sh, but they are usually for some
# few and special devices, e. g. ISDN devices.
#
# Todo: Check dead links ([ -L $FILE ]), check parameters of existing nodes
#
# I made this script for OpenSuSE and Debian because Debian Lenny some day 
# lost the device files for my USB keys, USB card readers and USB scanners, so they
# could not be mounted and not be seen by "fdisk -l"/"scanimage -L", although the 
# kernel messages did show the devices. It seems a preveously booted OS initilazed
# the hardware so that Debian could not initialise correct (long ago i saw similar
# problems with SuSE), so this script is a workaround; the clean solution is a cold
# start with at minimum one minute no power.

# Version 1.1, 2009-06-24, Status: mature for OpenSuSE and Debian Lenny.
# Version 1.2, 2010-03-29, Addes i2c devices and corrected ttyUSB part.

# Uncomment the next line for debugging/testing or simply see the script working.
#set -x

# Wait one minute to give the device nodes and links enough time to appear at /dev.
