    Random keyboards, even connection to EHCI/OHCI seemed to make difference.
    We have been doing some experiments with Alan during OLS and it seemed
    quite hopeless.

    A few keyboards we have been testing with seemed to be losing keypressess
    when coming out of suspend (if and only if the root hub wasn't suspended
    too, etc. Magic).
