This chunk seems like a copy of the patch Gustavo Padovan just
submitted? Should really be listed as a precondition instead of
included here, should it not?
-----In your opinions, it is better to declare this defining in the option.c file, but not usb.h file, right?

I guess this means that the device specific entries matching this could
and should be removed, does it not? All these seem redundant with your
patch:
------The new matching rule is independent of the special product ID, so it can support a series products of Huawei Data Card.
-----The following matching rule is only for the specific product, and it is covered by the new matching rule, so I think that we can remove the following matching sentences.

I see that the holes I know of are there, like protocol 0x08, 0x09 and
0x11. You wouldn't happen to have a complete list of those as well? I
am interested in the ones which can be expected to work with the
qmi_wwan driver. Currently we match
0xff, 0x01, 0x09 (along with a 0xff, 0x01, 0x08 data interface)
0xff, 0x01, 0x11
0xff, 0x01, 0x39 (along with a 0xff, 0x01, 0x38 data interface)
but I suspect there are more variants which could be handled by that
driver.
------Sorry, protocol 0x08, 0x09 and 0x11 is defined as the ECM port, they are supported by other kernel driver, but not option.c driver.
------So, we don't declare them in option.c.

And should the new entries be sorted with the other Huawei entries?
Putting them in front of the Option entries looks a bit strange
-------OK, we will improve this, and then update the patch.
