so you will not get debug info on linuxbios stage. and some later stge of Linux kernel you will get some out put even later than from vga console.
yes, but ... that's how it goes. Very few people want to see linuxbios anyway.
Many years ago I did an experiment, and was able to set things up so that linuxbios log buffer was picked up by the kernel, so you could do a dmesg and see linuxbios messages. I think this might be useful to revive.
I just don't see us putting a fully capable usb stack into linuxbios, it will not work as well as the linux usb stack.
