First of all thanks for your comments!

So it seems to me the only way is to write it our own. Or are there any
more ideas where to "borrow" code from?

Writing a own GRUB USB driver seems to be a complicated task, starting
with the three standards UHCI, EHCI and OHCI.

Furthermore I have no experience with GRUB drivers! Is there any
documentation besides the source code?
