I've just updated the keyboard firmware and the touchpad firmware on my first-batch ISO PineBook Pro, using the community updater, and the two steps went as expected. Strangely, something inside the laptop produced a hissing sound until the second step got completed; the sound was there before and after power cycling the laptop, upon the completion of the first step. I wonder what was the source of the hissing sound? The keyboard controller IC?
I've also completed the third, flash-kb step, which unfortunately caused the Fn + NumLock key combination to stop working. The green LED still turned on and off as a result of depressing the Fn + NumLock key combination, but the respective "numpad" keys still produced letters instead of numbers with the green LED illuminated. I haven't attempted to debug that; instead, I've repeated the two steps, ending up with the latest unpatched version of the keyboard firmware.
In this state, my ISO PineBook Pro should have the same keyboard firmware and the same touchpad firmware as the ISO PineBook Pros that were made in the last batch, if any ISO variants were actually made in the last batch. Unfortunately, the firmware update made no improvements to the touchpad, i.e. the touchpad is still laggy and experiences the same initial delay as before the firmware update.
As a note, the value of the "Synaptics Noise Cancellation" paramater remained at "0, 0" all the time.
Edit: The initial delay is also easily noticeable when using the touchpad on the virtual console, using gpm. However, it's also rather easy to not notice the delay, especially after using the touchpad for some time, because the human brain seems to keep trying to "weed out" such short delays or time shifts, in an effort to present a coherent image of the surroundings.
