Description
The keyboard driver input/keyboard/at/0 is opened twice by the input_server or some other app during startup.
After the first open(), it's immediately close()d. This is redundant, and wasting time, as keybaords may need 500ms or more to be reset, which is done during open.

the keyboard device addon was opening devices on scanning to be sure they were valid. we don't care and now open them when starting them. fixed in revision 16369.
