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!
