Yes, that's the expected brokenness. If keyboard input works at all,
it is not likely to be a fundamental problem. However, the working
parts probably need races to work.
I really miss the LEDs on a keyboard without them. Under WinXP, there
is a utility to display the caps lock state using only 10MB of memory.
Under FreeBSD, I don't have such bloat and have to fly blind.
