Interface 1 on this device isn't for option to bind to otherwise an oops on usb_wwan with log flooding will happen when accessing the port: tty_release: ttyUSB1: read/write wait queue active! It doesn't seem to respond to QMI if it's added to qmi_wwan so don't add it there - it's likely used by the card reader.
