Are you sure? I didn't try it yet, but according to
http://www.spinics.net/lists/linux-usb/msg32912.html
it should be possible to use a Linux machine as USB debug port device.

I haven't checked whether the patch (or something similar) landed in
mainline.

Once I find time I wanted to try it myself, as the Abit A-S78H I am
trying to port coreboot to, doesn't have serial ports, as well.

Cheers,
