I finally got my NL-602u, and wanted to report that it works out of the box 
gpsd 3.6 via "gpsd /dev/ttyACM0". It performs very well under rough conditions
(small window, dark rain clouds). Positioning is quite accurate and a fix is 
acquired. Whats really nice about it is 115000 baud rate and 5Hz update 

Maybe someone can add it to the hardware list on the homepage.
