There are other cases, where that memory can be freed at device disconnection time. Also, IIUC, this very first try isn't possible: when you unregister the tty interface, there'll be no close(). Then you can't wait for that to free the port memory and friends. | One of tricky things is if it's possible to | achieve without excessive modifications of all the usb-serial | drivers. Sure.
