The keyboard driver model changed in 4.2. In previous versions, USB
keyboards sent their data directly to GWES. Now, keys are routed through
the layout manager. There must be a builtin keyboard driver that provides
this support. If you don't already have a keyboard driver (if your other
buttons are handled in a different manner), you can just add the NOP
keyboard. That driver will provide the functionality necessary to route the
USB keyboard up to the gwes.

If you do already have a keyboard driver, you must update it to add support
to properly route data from USB keyboards. It's just a handful of
functions, they are documented in the 4.2 help.
