OK so it turns out I lied. It doesn't always work on Antergos either. It seems to happen randomly and how to get it working again is also a mystery. Resetting BIOS default does not restore it, and neither does booting into Windows - where it's not working there either. I unplugged both the power cable and the USB mouse then just kept restarting it until it mysteriously started working again. Attached is the full dmesg logs for both working (YES) and not (NO). Here the pertinent parts:
