grub2 + xhci

[Roma Jam]

Dear Grub-devel Subscribers,

Hi everyone. 
Does anybody work on grub2 xhci implementation at the moment?

To speak briefly, we have an idea to use native drivers but we ran into the 
problem that native drivers does not work properly on hosts with xhci.

I wonder is there any chance to connect with someone who are developing or have 
developed xhci driver for now?
Or maybe to get the repositiory url?
Any information would be usefull.

Anyway, any sugestions are welcome and please feel free to reply me via this 
emal.

Sincerely,
Roman.
