- 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.
