Ultrafast boot with usb keyboard

[Mark]

Greetings,

thank you very much for this wonderful tool.
After a lot of reading I have solved almost all the problems with rEFInd.

I have a gigabyte Z77x-up5 motherboard with full uefi (CSM DISABLED). When I choose ultrafast boot in bios, it boots so fast, that my usb keyboard doesn't work so I can make a selection in rEFInd. Bios does have option for usb devices support in ultrafast mode, but enabling it doesn't work.
This is probably bios fault, but I was thinking if you have any suggestions.
I was thinking a different approach. Maybe if I put a generic usb/keyboard efi driver in the drivers folder?
Do you know where I can download such a specific driver so I can test it?

Thank you for your time.

It's unlikely that a separate driver would help. As I understand it, the EFI fast-boot options disable part or all of the USB initialization to save time. In order for a separate EFI USB driver to work, it would have to do the USB initialization itself, so there'd be no time savings vs. letting the firmware do it itself.

That said, I suppose it's conceivable that your firmware is completely bypassing USB initialization, whereas some partial USB initialization might be sufficient to get the keyboard working. Thus, if you can find a standalone USB driver, you could always give it a try. (I recommend doing a second rEFInd install in another directory, like EFI/refind_test, and putting your test driver there. This way, you won't risk making your computer unbootable should the driver cause problems.) I don't know of a driver you could try, I'm afraid.
