I did have a temporary issue with both my Eon's not connecting to any computer with either lead in any number of permutations.
Basically I'd cleaned the contacts and I suspect the leads hadn't dried. I have early Eon's with the gold gold coloured contact, and I do need to clean them and the contacts on the leads fairly frequently
@JohnnyC DM5 is also used for the deep set up and config, and firmware updates of the Eon not just for dive logs - I personally use Mac dive for my data, but do also back up into DM5
