Linux "EHCI Debug Device gadget" driver found in recent kernel)
to retrieve the coreboot debug messages (instead, or in addition
to, a serial port).
This feature is NOT supported on all chipsets in coreboot!

Intel platforms have hardwired the debug port location and this
setting makes no difference there.
Hence, if you select the correct port here, you can speed up
your boot time. Which USB port number refers to which actual
port on your mainboard (potentially also USB pin headers on
your mainboard) is highly board-specific, and you'll likely
have to find out by trial-and-error.
