Actually, I have zero USB devices plugged in. The board has 8 USB ports
(including one for debug) and I bought an add-in card (6 ports) which I
wanted to test for debug support.
I wonder whether I can add two more 6-port cards with one debug port
each to that machine. ;-)
My goal is to make sure the coreboot USB debug code works well with
plug-in cards. That's needed for boards without serial and without USB
debug support (mainly IBM boards).
