The Compal EXC-T1 is a Qualcomm MDM9207-based LTE modem which reports "EXC-x1" as its USB product string. It exposes its QMI function on interface 5. Add a fixed-interface match for the QMI function. Tested on a Compal EXC-T1 modem using an Ubuntu kernel build. Interface 5 bound to qmi_wwan and exposed cdc-wdm2 and wwan1.
