Update: I plugged the BU-353 into one of my debian boxes and did the following... 


grunt:~# apt-get install gpsd gpsd-clients
grunt:~# dpkg-reconfigure
grunt:~# dmesg | grep ttyUSB
 usb 1-6: FTDI USB Serial Device converter now attached to ttyUSB0
 usb 1-9: pl2303 converter now attached to ttyUSB1
grunt:~# stty -F /dev/ttyUSB1 ispeed 4800
grunt:~# cat < /dev/ttyUSB1

... and out streamed lovely lines of GPS data.

That was easy! That's is what I was expecting.

So there is nothing wrong with the BU-353.

One of the questions i have seen posted on the askubuntu forum (http://askubuntu.com/questions/30569/how-to-use-gps-receiver-bu-353) suggests if it is not working it might be a missing kernel module. Yes, the kernel spots the Prolific USB driver but does it need a special SiRF Star IV module that I might be able to find, compile & modprobe?

Any ideas/help will be gratefully received.
