According to ALPS, our keyboard/touchpad never needs to be reset on
If you don't mind the slightly stilted English, here's the exact words.
Reset command (0FFh) need not be sent to the keyboard.
When PowerUP is done, the same operation as the reset command is done.
When the restart and the movement of the keyboard are abnormalities,
the reset command is used.
