Well, color me a fool, or something. I had this issue reproducing regularly yesterday, and today I cannot get it to reproduce at all. Logs are clean today. I've shutdown completely and restarted a few times and all seems to be fine. No idea how it cleared up, but it seems fine now. Self healing, perhaps?

Any ideas on how to capture them? It happens on boot. I can check the logs and see if they are logged, but other than that I'm not sure I can grab them in time.

This is kind of a big issue for me, as I'd rather not lose data from drives not unmounting cleanly

I got this working just fine in the latest released LiveCD download. The only change I made was to plug the cable with the keyboard connector into USB 3.0, per Corsair's instructions (USB 3 provides enough power). It works like a charm! I'd say this ticket could be closed.

Here's the output from journalctl -f:

I'll grab this for you this weekend; I've been sick and haven't had a chance to tinker.

Excuse me for my density, but is this in the download ISO? I need to be able to boot off of it to test. :)

Thanks Corsair! /s

Firmware is 2.05 (latest available)

Here you go.
