So if you check the "save libdivecomputer logfile" or "dumpfile"
checkmarks, NO DIVES WILL BE DOWNLOADED.

It will *only* generate the dumpfile. It's on purpose - but badly
documented - for debugging purposes.

So the very fact that you have dump-files makes people worried. If you
have a dump-file, we don't *expect* the dives to get added to the
subsurface logs at all. See?

Dirk - that interface sucks. It's confusing. It's horrid. The dump/log
thing should be somewhere *far* removed from the "download dives"
button. A whole different "debug libdivecomputer" menu item or
something.

Erick - a few things to look out for when downloading dives:

 - as mentioned,do *not* check the dumpfile/logfile entries, because
they turn on the debug-only mode, and the *only* thing you'll get is
that dumpfile and logfile.

 - by default, subsurface will ignore older dives if it finds a
matching dive that it already knows about, so be careful if there is
*any* chance at all that the date/time of the dive computer has been
changed. You can use the "force download all dives" checkmark to make
subsurface ignore the fact that it aleady saw one dive, and will make
subsurface look if you have older dives that it doesn't know about.

 - The number of dives that the Zoop says it has in the logbook is
*not* the same as the number of dives you can actually download. Zoop
(and all other Suunto dive computers, and most dive computers in
general) have a separate "statistics over the lifetime of this device"
and "sample data for the last N dives". The Zoop only remembers
roughly the last 10-20 dives or so as individual dives (depends on how
long they were and what your sample rate is)

So there might be a number of things that are wrong, that aren't wrong
in subsurface itself. It's hard to tell from your description.
