Does that mean all the keyboards are standard keyboards (round connector)
that are connected via a USB-to-keyboard adapter?  If so, do you have
another one of those you could try?

Do the problems occur in any graphical environment, or only Trinity?  What
about with some other Linux running from a live CD?

Are you plugging the keyboards directly into the computer, or into the
docking station?  Are the problems the same either way?
