AFAICT, on x86 it only supports using either a console capable serial
port (so you could do that over USB if you have USB serial console
support built-in, but most people I know don't compile that in, and in
fact that is the only reason that i compile USB serial support in
instead of making it a module), and an AT compatible keyboard with any
console option.  It would be really nice to have USB keyboard support in
there so that you don't have to reboot with special options and extra
hardware plugged in to get to the debugger, although doing something
that supports more than just the HID boot protocol will probably be tricky.
