Its more a OSELAS-Community related question than PTXdist specific. So I
forward it.
Take a look into the Mini2440 BSP which has the same issue:
$ cat
configs/platform-friendlyarm-mini2440/projectroot/lib/udev/rules.d/10-mini2440.rules
#
# some Mini2440 related settings, due to the kernel enumerates them differently
from time to time
#
SUBSYSTEMS=="input", KERNEL=="event[0-9]*", KERNELS=="input[0-9]*",
ATTRS{name}=="gpio-keys", SYMLINK+="input/buttons"
SUBSYSTEMS=="input", KERNEL=="event[0-9]*", KERNELS=="input[0-9]*",
ATTRS{name}=="S3C24XX TouchScreen", SYMLINK+="input/touchscreen"
SUBSYSTEMS=="input", KERNEL=="event[0-9]*", KERNELS=="input[0-9]*",
ATTRS{name}=="pwm-beeper", SYMLINK+="input/beeper"
You must do it in this way, due to the kernel brings up the drivers
concurrently. So there is no guarantee of the device order even
if you do not add new devices!
