Ales, I'm thinking of the EHCI hand-over. In the case of EHCI handover beeing successful within the timeout, you never clear the USBLEGCTLSTS register (SMI's). You do that in the other cases however. Why? I can not think of any case of a successful handover with SMI's still enabled. To what purpose? A buggy BIOS would maybe act upon such stuff? Maybe thats a case for lost devices etc? Also, I've been toying with the black magic EHCI hand-back. I've gotten it to work for some machines. The problem with GRUB and USB is that if you enable USB you have no more control over USB in case a OS needs input before loading it's own USB stack. Do you have any experience with this? Could we make such code execution optional on environment etc (because hand back is even more buggy than everything else.. :)) Maybe users can use it in corner cases when they need USB-input with usb-support in GRUB... if it'll work on their hardware that is.
