Quectel EP06 (and EM06/EG06) supports dynamic configuration of USB
interfaces, without the device changing VID/PID or configuration number.
When the configuration is updated and interfaces are added/removed, the
interface numbers change. This means that the current code for matching
EP06 does not work.
This patch removes the current EP06 interface number match, and replaces
it with a match on class, subclass and protocol. Unfortunately, matching
on those three alone is not enough, as the diag interface exports the
same values as QMI. The other serial interfaces + adb export different
values and do not match.
The diag interface only has two endpoints, while the QMI interface has
three. I have therefore added a check for number of interfaces, and we
ignore the interface if the number of endpoints equals two.

That's annoying, but hardly surprising. They obviously try to make life
as hard as possible for the drivers. I wonder what the Windows drivers
do here, if there are any? Or are these modules only used in embedded
Linux devices?

Could this break if more/other functions are enabled? Are you sure
there can't be any other type of serial function with 3 endpoints and
ff/ff/ff? Well, I guess no one knows for sure... And this is more than
good enough until it breaks. Thanks for solving the puzzle. Looks good
to me.

Hei Bjørn,
Thanks for the feedback!

There are Windows-drivers, but I don't have access to them (or a
machine to test on if I could get them). I would not be surprised if
the modules turn up in Windows-machines, they seems to be quite
popular. EP06/EG06/EM06 all refer to the same module, they just have
different connectors. P is mini-PCIe, G is embedded and M is M.2.
Perhaps the assumption is that Windows-users wont mess around with
these settings? :)

I forgot to include the listing of all interfaces in my commit, so I
have inserted it at the bottom of this reply. With the current
firmware and interfaces, only QMI has three endpoints and ff/ff/ff. I
guess we just have do as you suggest, wait and refine the approach if
or when something breaks.
Output of lsusb -v for EG06 with all interfaces enabled (I have
checked that EP06 produces the same output):

I'm sure they could add another serial interface with ff/ff/ff and 3
endpoints, but I don't know what else we can do to make this device
work correctly. I double-checked the permutations & logic and it makes
sense to me.

Would it be possible to have this patch added to stable? I checked
both the 4.14-tree and the stable queue, but could not find the
patch/upstream commit.

Please ignore this request. I discovered patch does not apply to 4.14,
so I will do a manual backport and send to stable.

Blah, it is clearly not my day today. I discovered that my 4.14 build
directory was dirty and that the patch applies fined on top of
4.14.78. Sorry about the extra noise and please do not ignore my
request for stable :)
