+Subject: [PATCH 1/2] usb serial gadget: no TTY hangup on USB disconnect [WIP]
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+We may want to maintain the TTY over USB disconnects.
+
+This is useful when we have a terminal console to a host which
+power-cycles or for other reasons resets the USB host controller.
