OpenWrt 18.06.8 (x86 Geode) and ancient 3G USB modem Huawei E1820.
Installing it using " How To use LTE modem in QMI mode for WAN connection" guide.
Looks like usb-modeswitch doing it's job changing 12d1:1446 to 12d1:14ac.
But after it qmi_wwan do not autobind device and /dev/cdc-wdm0 do not appear.
If I manually do:
Ofc. i can add this echo to rc.local like ppl do with new (unknown to driver) equipment and so on, but why such ancient device is not autobinded by qmi_wwan driver? Something wrong with device (if's cls, sub, prot, etc.)?
The 02/06/ff class is unexpected. Huawei have been using a vendor class scheme "forever". But we can add this to the driver if you can confirm that it works. That means getting qmi replies. Run uqmi or qmicli and verify that you can talk to the modem.
The driver does not verify any qmi support. It will happily bind to almost anything with 2 bulk and 1 int endpoint. This is why you have to verify using userspace tools
Device is old, maybe the first owner did something with it in past.
I know it's from ebay and was non-locked to any carrier (sealed unlocked).
Is it possible for user to overwrite device's cls, sub and prot somehow?
Are there any known default settings/info for this/such modems to check it?

uqmi: (modem is w/o sim-card, i have no 3G sim-cards atm and we have those "corona restrictions", so as is):
P.S. Btw, Is it correct that I use "qmi-wwan" way?
Will it (QMI) give me best speed results with this modem or other ways possible/better (mbim, ncm, whatelse)?
I have no spec of the scheme, but i looks like they assigned protocol "9" to QMI with two inferfaces and protocol "7" to QMI with a combined interface. And use a few more bits in subclass and protocol to indicate other stuff which is irrelevant to the driver. All of these are using the vendor specific class (0xff)
Nice. That's good enough for me. So I just sent off a patch. And then noticed that we already have that device in the table, only using interface number matching:
Which matches the number of your 02/06/ff interface. So this device should just work by default. Did it not? Do you have an dmesg sample showing what happens when you load the qmi_wwan driver without writing to new_id?
Doesn't look like you have any other option (except ppp, which will be far worse than any of those). But QMI will probably also be best due to the simple framing, using one USB transaction per IP packet.
What means digit 1 here, after VID and PID? Number of needed interface to trigger autobind?
I was doing some "experiments" with AT^U2DIAG today.
Found some possible values in internets (not all work as expected tho)
One of it was AT^U2DIAG=36 which was described as (MDM:0,NDIS:1,DIAG:2,PCUI:3), so SD and CD and something else are disabled.
When i set it to this AT^U2DIAG=36 - then autobind trigger. And it was only one value which triggered autobind.
(Other tested values were 41, 256, 276)
In this case device is look like (notice different PID):
But it's for sure not default mode/value for this modem. So i set it back to 255 wich is default (or at least i think so)
And for dmesg w/o echo to new_id:
It's same, but w/o last 2 lines (MAC is random ofc. each boot):
qmi_wwan 1-2:1.1: cdc-wdm0: USB WDM device
qmi_wwan 1-2:1.1 wwan0: register 'qmi_wwan' at usb-0000:00:0f.5-2, WWAN/QMI device, 0e:19:ba:e3:40:8b
Also i did clean install of 19.07.2 x86 Generic on another hardware (VIA Artigo A1100) and tested this modem on it (same, no autobind w/o echo to new_id). ~900 lines of adventures step-by-step.
Do i need to add full dmesg w/o grep -i usb?

fresh "install", opkg install usbutils

^C"Failed to connect to service"
I'll try to figure out a way to handle this. We can't just drop the last "fix". It is necessary for other devices. But I'll figure out a way to support the comm class QMI interface on the E1820.
Thanks for your persistence, convincing me that there was a bug here
Was a fix / upstream bug ever submitted for this? I seem to be running into it on another system, as qmi_wwan is not being bound. However I don't see any related patches or bug reports in the kernel.
Nope. The latest official usb_modeswitch binds the option driver after switching, though, so the problem is solved in userspace. However, OpenWRT's usb_modeswitch is not the same as usb_modeswitch in all other distributions, so the problem is unsolved for OpenWRT users.
