Yes, this is what is holding up the patches to media_build. The bug appears to be a race condition that appears in get config with some usb controllers. Josu, your patch is for the older hg version on s2, so this will not work on media_build. I have being trying to a way to do it without the bus lock, but can't I will try and finish the patches tomorrow. Regards Malcolm
