Problem: when reading, it finds the device, but then it keyboard powers off. Here is the output:

This might be relevant. Maybe it is not configuring device beforehand on mac os. Some drivers (like those for mac os) might not configure on initialization.

@WilliamFernsV3 can you run list right after the ISP command is sent and "keyboard powers off" and share its output, without replugging the keyboard? Perhaps you can also run lsusb or ioreg -p IOUSB -l -w 0 at the same point too and share its output.

Same issue with K642. Keyboard blinks, I tried it on windows.
