The correct solution would be to use RUN rules. Next best, udevsettle
will work (but will obviously wait for *all* pending events, which may
or may not be a problem).
But if you already know the expected device name then waiting for it
in a loop for a few seconds would work as well.


BTW, the race-free way to use udevsettle is:

mkdir -p /dev/.udev/queue/
modprobe ...
if ! udevsettle; then
  echo timeout
fi
