Ok. Let me reconfirm the meaning of these opinions.

"auto"
	if port without device, turn off power directly.
	if port with device, turn off power when the device is suspended.

"on"	the port's power must be on.

"off"	the port's power must be off.

Right?

Maybe the "auto" setting should be renamed "active".  Then "auto" can
be used for:

	If the port has a device, turn the power on.
	If the port doesn't have a device, turn the power off.

And plugging a new device into a port that was powered off is going to
cause the power to come back on, right?

   How plugging a device can be detected on unpowered port?
