Note that if this device is like the MC77xx, then it will switch control protocol based on protocol snooping and *not* the selected USB descriptors. So if you probe it as MBIM then it becomes MBIM, regardless of whether it is driven by cdc_mbim or qmi_wwan. It does not really support switching modes without being completely reset. You should let udev select a mode as soon as it is discovered and stick with that.
