    That sounds similar to something I read in the docs for SCM's epat
    (yes, I am a one horse show - that's the only chip I have)
    protocol. While you can get the devices to enumerate themselves it
    might be difficult if the enumeration-time daisy-chain order changed
    and had to be re-enumerated (and how would the driver know to do that?
    I don't know.)

    As I recall the devices would be 0-3 assuming all the peripheral
    controllers were SCM epats... It wasn't clear what happens if devices
    are moved around or even if there are multiple devices which want
    IDs. I suppose this is related or maybe even the same thing you were
    talking about. Either that or I'm just making a fool of myself.

    BTW, vote for me. I'm running for mayor in Minneapolis MN ;-)
