Ok, that sounds like a good start. I'm a little fuzzy on the details though. Does that mean you think we should add an "auto" option to the sysfs file? Then when the file is set to "auto", have the kernel turn off ports that don't have a USB device connected to it. Have the kernel set the default sysfs value to auto for unpluggable ports. Or do you think userspace should set the sysfs file to "off" after verifying the port is unpluggable through new sysfs files?
