With the duplicate (required?) entries, delay of 1000 msec for both works, delay of 100 msec for both fails with:
Jun 18 23:48:23 laptop NetworkManager: <info> (ttyUSB0): found serial port (udev:GSM hal:)
Jun 18 23:48:23 laptop NetworkManager: <info> (ttyUSB0): deferring until all ports found
Obviously anything higher than 3000 (I tried 6000) will fail, since max delay is 3000.
