I can do that in about 15 minutes if you give me the device ids for the
usb debug device that you wish to have.

Or you can also use the generic usb-serial driver today just fine with
no modification. Have you had a problem with using that option?

We are talking about using USB debug device/EHCI debug port in LinuxBIOS
in legacy free PC.
Because one AM2+MCP55 MB doesn't have serial port.

I guess Eric is working on USB debug device/EHCI debug port for
earlyprintk or printk.

Well, earlyprintk will not work, as you need PCI up and running.

*grin* I just generated the bootlog below. So I think I have
it working. There is a lot of cleanup left and I need some sleep but
it works for me. I will generate a patch to start the conversation
after I wake up.

And I have some code that barely works for this already, perhaps Eric
and I should work together on this :)
