[Bug 663372] [NEW] With multiple keyboards, pressing NumLock effects all keyboards

[Burton Samograd]

Public bug reported:

On a system with multiple USB keyboards plugged in, pressing the NumLock
key on one of the keyboards will cause all of the keyboards to behave
like they have had their NumLock pressed (both LED will change and the
behavior of the number pad).
