I have got a bit power on disabling EHCI, but it could happen just because device itself went into the D3 state. C3 stats doesn't changes on that.

There is one question appeared, is there any way to deny driver attachment for some specific device to left it is D3 state? For example I don't need some specific USB hosts and PATA controller, but I can't disable them with just not loading the driver. There is alike DF_ENABLED flag I have found, but I haven't found any external way to reset it. :( -- Alexander Motin
