qmi_wwan is supposed to bind to interface #2 on that device.  I don't
know why it hasn't.  dmesg output would be good.  Maybe there is some
error?  Or maybe some other driver has bound to that interface already?
It is blacklisted in the option driver, but if you (or some script) has
messed with dynamic IDs then it could still be taken.

A few commands to try debug this further:

 lsusb -vd 1bc7:1201
 ls -ld /sys/bus/usb/devices/*/driver
 dmesg
 cat /sys/bus/usb-serial/drivers/option1/new_id
