This should indeed be the version I had in mind as well - hell, already 1.5 years since then, and still no EHCI upstream... >=20 > If someone is interested in this partially ported patch, I'm happy to > share, but it will at least need some attention to make it compile. > After that, lots of tests need to be done and probably quite some > bugfixes are required.

Either it's already in a good shape to get it merged as experimental feature. Or I will pick it up in git tree, collect patches as they fly in, and will keep on pushing it upstream. I can't promise spending much time on hacking, but integration work, basic testing, and some more or less helpful comments should be feasible.
