can't download Oceanic VT3 on linux

Thu Mar 6 18:20:22 PST 2014

Hi,

I'm trying to download from my VT3. I've built libdivecomputer 0.4.2 on 
Linux (64-bit) but downloading is very slow and eventually fails. I've 
tested with both Subsurface and using the "universal" example. It does 
retrieve some dive data ok though.

Downloading my VT3 does work on Windows though, using Diving Log 5.0 
(includes libdivecomputer 0.4.2, 32-bit) or the "universal" app binary 
which I downloaded directly from the libdivecomputer.org site.

I've included a bit of the output log from "universal" on linux below. I 
checked that nothing else has the port open with lsof - earlier 
modem-manager was running but I've killed and removed that now.

Any suggestions?

Thanks,
Hamish
