I also have that problem occasionally, and the same fix works. But the
USB socket is in a rather inconvenient place. The mouse still works on
these occasions so a custom menu item to click that ran a command to
emulate the unplugging and re-plugging of the keyboard would be nice to
have.
Does anybody know a command that will do that?
Full power off-on cycle (not just USB reset) may be initiated by
uhubctl. The question is whether USB hubs on the motherboard support
per-port power control.
Some keyboards may be rather sensitive to USB port voltage. A model with
built-in HUB (for e.g. a USB pendrive) did not work when plugged into a
laptop, but there was no such an issue with desktop. I would not be
surprised if another device requiring enough power on the same bus might
still cause trouble with keyboard.
