Alright then.  I just checked in your last USB patch, after reviewing it:


I agree it's best to commit it.  It has a few minor problems, but this is
much better than leaving it to bitrot.  Then we can work on fixing them more

Let's enumerate them again:

  - OHCI works on qemu but hasn't been tested on real hardware.

  - --enable-grub-emu-usb isn't yet known to work.

  - There might be endianess issues affecting powerpc (note: we aren't
    building it there yet, we'd have to move PCI support to i386.rmk first)

  - A few parts of it are marked "XXX".

I'll add one more to the list: keyboard support wasn't included in this
patch.  I'll look into your other pieces of code and retrieve a working
keyboard driver.

Other than this, massive storage on UHCI should work fine.  See
http://grub.enbug.org/USBSupport for details on how to use it.

  how) you may access your data; but nobody's threatening your freedom: we
  still allow you to remove your data and not access it at all."
