+   If the value read is "off", then writing "on" (or '1', 'y',
+   'Y') to this file will enable power to the interface and an
+   attempt to boot and possibly enumerate it will be made. Note
+   that on errors, the interface will again be powered down.
+
+   If the value read is "on", then writing "off" (or '0', 'n',
