Haha, this ended up being the HHKB Professional 2 USB keyword that was
hooked to my desktop.  Even when not using it, it appears that the small
USB hub that is built in the keyword sends noise to the line and causes

I should probably de-solder that near-useless thing from this otherwise
fine keyboard.
