I'm on the wrong machine just now, but I found when I specify usb3 and
then usb strange things happen. My comment was check what the changes to
the script do, it is not always what is expected. On this machine it is
pretty good. my config line is firewire snd usb3 usb i8042
I'm not sure why I left it this way actually as I do not use FW... I think
I have the port turned off in bios. Anyway, the usb ports are priority 75
and 74 and i8042 are 70 and 69... not 5 apart. On the netbook it is even
stranger.
