The value's actually something we have been using as a rule of thumb
while doing outb to port 80. Don't thin
you could use io delay, one outb uses roughly 1us iirc.
On LPC, yes -- or 0.5us or something like that. On ISA it's
a lot faster, on PCI too -- better do 20 or so outb's to be
safe. Or use a *real* timer instead, you'll have to abstract
this for portability anyway...

Yes, I adapted the code to used in LinuxBIO

Thanks for the code.
In LinuxBIOS,
I put usbdevice_direct.c in lib/, and call it from usb2_init in
mcp55_usb2.c
Got
"No device in debug port"
Waiting for cable, hope to get that cable next Tuesday.
Will create usbdebug_direct_console.c in console/ for linuxbios_ram
code.
also usbdebug_direct_s

Not all of it though. LinuxBIOS will probably do just enough PCI
setup to talk to the EHCI controller and use the debug port _very_
soon after power on.
