Sorry for possible confusion, but I missed these IDs the first time I checked the driver sources.
1e0e:9001 is present in both option and qmi_wwan and there is no need to add them manually via new_id. If there is a desire to use it in MBIM mode that could be achieved by sending AT+CUSBCFG=USBID,1E0E,9003 to /dev/ttyUSB2
