There's a USB Panda display?

I bought two of the original parallel port Panda displays years ago.
Recently wasted a lot of time trying to get them to work. The Windows
diagnostic tool program works perfectly - sending patterns to lights
and running them. But try to use them with klh and they initialize
with a few random lights on when you start it and then never change at
any point until *hardware* power is cycled. Evidently there's
something screwy and the support for them was never actually
incorporated into klh and/or the final Panda TOPS-20 release.
