mind sharing your dmesg to the list?

This is a usb-to-serial converter, should normally work out of the box.
I successfully attach rev 1.10/3.00 of it on snapshot.
I tried "cu -l /dev/cuaU[0..3]" to no avail, normally there would be
the raw output of the NMEA message stream; in particular on /dev/cuaU0.
What's that "no avail"? If the uplcom doesn't attach, it should error
out with 'cu: open("/dev/cuaU0"): Device not configured'
You could try
tail -f /var/log/messages
and inspect what gets logged when you attach or detach different devices
in different USB ports.
