AIS Receiver USB dongle

This AIS receiver is cheap , consume almost no power and is simple to connect (USB dongle):
It works on Windows with a supplied driver and is recognized directly by my Linux kernel 2.6.35 (Ubuntu 10.10) as /dev/ttyACM0. Output is NMEA readable by OpenCPN. Resuts as good as when using my FT857 + sound card + AISMON under Windows or FT 857 + sound card + GnuAIS under Linux.
