Anthony just pulled EHCI upstream.  Yay.
Going backport a huge stack of usb patches.

Setting CondNACK just in case because of the sheer number of patches.
They are pretty much local to usb though, so I don't expect that much trouble.

Comment 4 Gerd Hoffmann 2011-06-01 16:03:28 UTC

Oh, and just for the record: I want EHCI have tech preview status in 6.2.
It didn't got enougth real world testing.  Also some important features such as migration support are not there yet.
