Hi,

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

http://lists.gnu.org/archive/html/grub-devel/2008-08/msg00604.html

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
easily.

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.

Thanks, I am happy it is merged now.  It would help if people reported
success/failure with USB support.

It is even certain :-)

Right, this shouldn't be too hard as the code was there.  But I have
seen you submitted this already.
