Hmm, it looks like your device has in fact switched to modem mode ...

It's not unusual for some devices to provide their "install storage" again after the mode switching. I'm just wondering which program or event is responsible for the switch.

In the dmesg output the mode switch process will show up with the following sequence:

... new high-speed USB device ... [just storage]
   ...
... device disconnected ... [device is switching modes]
   ...
... new high-speed USB device ... [modem and storage]

Can you spot that sequence after plugging ? It might take several seconds to complete with Huawei devices.
