According to the logfile, it works fine for your dive computer. The fact you 
have no dives is detected correctly and the test app reports success.

There are however some temporary errors. If you only get them occasionally, then 
there is no problem and the built-in error recovery will take care of those. But 
you shouldn't see many of them. But I can't tell from your log whether that's 
the case or not, simply because there is not enough data transferred.

Can you make a full memory dump? I would like to have some more test data from 
an "empty" device, and it will also allow to double check the number of packet 
errors you get in a larger transfer. Just run the universal app again, but now 
with these options:

./universal -l output.log -m output.bin -n "Oceanic Geo 2.0" -v /dev/ttyUSB0

Then send both the output.bin and output.log files.
