Firmware and USB Issues

I am using a Librem 13v2 (updated software/coreboot 4.7), and am running into the below firmware issues. Any advice on how to solve them would be appreciated.

$ sudo dmesg | grep firmware

Yes, I get many of those messages as well.

I get these error messages as well, any reason why?

Because there is no firmware to load. You can safely ignore these warnings, as the hardware work normally without firmware.

For my USB on the left side of the laptop, using an Libre 13v2 w/Coreboot 4.8.1 now, it is still unresponsive. It just stopped working one day (even before the Coreboot update), and I can no longer use the port for anything.

You need to contact us then, as it might be a hardware issue.
