This set of messages is what happens when no firmware is installed, thus it is 
not surprising that the device started working when you actually installed the 
firmware.

A kernel update should never delete the firmware, thus the procedure described 
in the GitHub repo's README.md is correct. A new kernel requires a rebuild of 
any out-of-kernel drivers, either manually or with dkms!
