You're really talking about whether or not a sub-device of a compound device is removable -- or at least, that's the terminology used by the USB spec. (The spec refers to ports, but you are attaching the sysfs attribute to devices.) According to the way you'd do it, in a USB keyboard with a built-in hub, the keyboard would be hidden, not visible!
