I'm also interested in what to do about the USB connectors. If it weren't for the metal plate part of the build I wouldn't worry about it so much if they broke I'd just fix them, but since there will be a metal plate really quite stuck to the top of the PCB I'd like to do something now before I start assembling my keyboard.
The connectors seem preeeetty solid, it's just that with the supplied cable the fit is very very tight! It takes an uncomfortable amount of force to make stuff go in or out haha.
I have a different cable I'm going to use.. same length but not nearly as stiff, but my instincts are telling me to drop some epoxy on each side of those connectors.
Thoughts?

I would recommend reinforcing before installation. Mine broke off during normal use and now it is useless :(. I put in a ticket on Friday and sent pictures, no response yet.

I wonder if some hot glue might provide a bit of strain relief. Anyone tried before on other products with micro USB ports? Those surface mount connections don't look very strong.

I would not use hot glue, hot glue will provide hardly any strength. I would go with the suggestion that is now in the instructions about adding some more solder on the top left and right of the connector.
Epoxy works really well, but it's really hard to keep it out of places you don't want it, I didn't REALLY get any inside the connector but it was just vaguely sticky and I had to clean stuff out with a toothbrush and some isopropyl alcohol and it was a pain.

In theory, a drop of rubber toughened cyanoacrylate should work as well, but we haven't tested that approach. It is nonconductive, but the danger is of it getting inside the connector case (as is when applying too much solder), so a more flexible/thinner cable is currently a preferred solution it looks like. Even if those thinner cables are possibly underspec as far as usb 3 standard goes due to thinner gauge, neither the PC connection nor the interconnect needs the full bandwidth.

what about putting a piece of perfectly trimmed paper over/around it before applying the rubber toughened cyanoacrylate or epoxy to prevent leakage?
