I have recently used some Huawei E3131s for a project, and all I can say is that Huawei puts out *a lot* of different capability devices with the same model numbers.  some have 4 modes of operation, some have 3.  The ones with 4 modes provided a CDC Ethernet device by default, the ones with 3 did not.  Huawei calls it Hi-Link.  There is a Huawei Proprietary / Confidential document that details all of the AT commands to switch modes into something USB modeswitch knows about.  Unfortunately, the commands t get from Hi-Link (ethernet) to modem is not there, and reading the _javascript_ from the browser is not there either.  The only way I know to get them into modem mode is the browser interface -

I have no clue if your issue might be related, but I hate these Huawei sticks because you cannot know what you are getting before you buy them.  Here are a few of my notes for your reference - BTW - I do not use NM on these, so YMMV..  I run them with raw PPPD since they are hanging off of stripped down OS PIs..  If you're as old as me and sold dial up internet access in the 90s, then some of these will be familiar :)
