Actually, on Ubuntu/Kubuntu, you are probably already set up with permissions;
by default, serial ports (including USB/Serial adapters) get set to group
ownership of "dialout", and in general when you set yourself up with an
account on installation of the system it adds you to that group.  

So really all you need to do is go into Xastir, add a serial GPS, and 
use /dev/ttyUSB0 as the port (if that's what it says it connected to
in /var/log/messages).

If you add more than one USB serial device (e.g. a TNC) you might start to have
trouble when you insert the devices in a different order (i.e. this time it
might come in as ttyUSB0 and next time as ttyUSB1).  There are ways you 
can assure that any USB device attached always gets the same name, but
I haven't ever bothered to figure it out --- I usually only have one USB 
serial device attached at a time, so they're all always /dev/ttyUSB0.
