I've been trying to get a ZTE MF60 3G modem working with MM/NM but even
though recent updates have provided some progress it's still quite not
working. It's not explicitly listed in the page of Supported Devices [1]
so I'm not sure whether there is some fundamental problem with the
device or is this merely a fixable issue somewhere in the stack.

Posted an update to the bug, at the moment it looks like the device
simply doesn't respond to the StartNetwork request via QMI.  Some of the
early hotspots are known not to implement QMI well, but I think we'll
want to test with a Gobi 1K (which is also NAS 1.0 and very early QMI)
just to make sure that still works.

Yeah, known issue. The MF60 doesn't play well with the WDS service in QMI; see

Quoting Bjørn:
"3G connection management is done using the built-in web server.  Does
not look like it can be managed by QMI.  But many QMI_NAS and QMI_DMS
commands are supported."

Anyway, I actually delayed QMI support in the ZTE plugin just because
of this device. MM 1.2 now allows QMI for ZTE devices, but we should
probably setup that blacklist that we talked about some months ago,
for devices like this one.

ok, thanks for the pointer and background information, it looks like
this is much more "fundamental problem with the device" than "merely a
fixable issue" then.

Does the modem expose a tty as well? The fallback of course is to make
it use AT+PPP instead of QMI; which is the purpose of the blacklist
suggested here.

I see /dev/{cdc-wdm0,sdb,serial,sg2,sg3,sr1,ttyUSB0,ttyUSB1} to appear
after plugging it in.
