i got my e3372 and switch its firmware to stick mode..but my pfsense is based on 2.3.5 running on alix 2d13..I check the dmesg when I put my modem:
ugen1.2: <HUAWEIMOBILE> at usbus1 (disconnected)
u3g0: at uhub1, port 1, addr 2 (disconnected)
ugen1.2: <HUAWEIMOBILE> at usbus1
u3g0: <HUAWEIMOBILE HUAWEIMOBILE, class 0/0, rev 2.10/1.02, addr 2> on usbus1
u3g0: Found 2 ports.
no ue0 device at /dev .. doesnt show the NCM interface..Can I load the NCM driver using 2.3.5??
Yes you can, you need to use the setport command from the AT command set for the modem to enable the NCM interface. I have another post with some details thrown in contained here: https://forum.netgate.com/topic/137637/huawei-e3372-will-not-reconnect-ppp-after-manual-disconnect-under-status-interfaces

In summary what you need to do is jump into the console and talk directly to the modem via the emulated serial port by running: cu -l /dev/cuaU0.0 or cu -l /dev/cuaU0.1 depending on which port it created and wants to talk on. Once in there run the command AT^SETPORT="FF;10,12,16" and then AT^RESET to reboot the stick. After having done this once, from herein the stick should present the NCM interface which is defined by the 16 in the command above.

PS - I can confirm this works on 2.3.x as I had a client on that version a while ago and utilized ones of these.

[2.3.5-RELEASE][root@pfSense.local]/root: cu -l /dev/cuaU0.0

Same no ncm interface after issuing these commands..

Ok can you show me the output of the following:

cu -l /dev/cuaU0.0
AT^SETPORT=?
AT^SETPORT?

Unfortunately I don't have one with me to check the config directly, however have you modeswitched the device out of mass storage mode? If not, you'll need to download and install usbmodeswitch by running this (from memory 2.3.x is on FreeBSD10 so this should be the correct version):
pkg add http://pkg.freebsd.org/FreeBSD:10:amd64/release_4/All/usb_modeswitch-2.5.0.txz
and then running this:
/usr/local/sbin/usb_modeswitch -J -v0x12d1 -p0x1f01

Running that will cause the device to drop out of mass storage mode and should present the interfaces. Let us know how you go. If I had a stick with me I'd go through the motions and post it up for you but unfortunately I can only go off some notes I have here from the last one I did quite a while back.

Issuing this AT^SETPORT=? command got an error answer from modem..here's the message after usbmodeswitch

this modem command gave me a solid blue light on the modem,,but no ue0 or cde interface showed up..

The error from usbmodeswitch makes sense now I think about it, you have the stick firmware loaded so as such the device when inserted won't present as a mass storage device. I have an e3372 with the stick firmware loaded at work, if I get a chance tomorrow I'll fire up a machine with 2.3.5 and see if I can make it work. As I'm not familiar with your Alix hardware the closest I can go to replicating your environment would be to install an archived version of pfSense-CE-memstick-2.3.3-RELEASE-amd64.img I have here on an amd machine. Is your alix similar or a totally different platform?

Oh thanks..its an old alix 2d13 i386..I think 2.3.5 doesnt work with 3372 in stick mode

bradtpt · Aug 8, 2019, 2:33 PM

Ahh ok, unfortunately netgate don't leave old versions online, I'll have to go digging and see if I can find a i386 installer kicking around somewhere. If you have a link or can dropbox it to me or similar let me know.
-edit- I just found this: https://mirrors.xmission.com/pfsense/downloads/pfSense-CE-2.3.5-RELEASE-i386.iso.gz and this: https://mirrors.xmission.com/pfsense/downloads/pfSense-CE-memstick-2.3.5-RELEASE-i386.img.gz so it looks like we're in luck.

I would be surprised if there's any difference between the 32bit and 64bit versions as far as this modem is concerned. The available tools should be identical.

I test this modem through vm pfsense 2.4 , ue0 and cdc showed up..I wonder if there is any new patch from 2.4 if_cdce.ko that was not included in 2.3.5

can you look at this: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=192345

stephenw10 · Aug 9, 2019, 11:28 PM

There are many, many differences between FreeBSD 10.3 and 11.1 which is what you're comparing there.

That link is broken.

the patch includes

head/sys/dev/usb/net/if_cdce.c
head/sys/dev/usb/serial/u3g.c
head/sys/dev/usb/serial/umodem.c

hope someone could port this patch on 2.3.5

stephenw10 · Aug 10, 2019, 4:04 PM

Your link was actually good, the bug server was down at that exact moment I tested.

Porting that is non trivial. You would have to rebuild a whole number of things there. You cannot just load a replacement module. And even after you had done that you would still be running unsupported, unpatched, 2.3.5.

Is there some reason you cannot just replace that ALIX with something vaguely current?

This alix will be deployed on our client’s remote area maybe this end of the month.I’ll convince him if he can rather buy a new hardware..I may use openwrt with this 4g stick if he refuse to shell out some $

stephenw10 · Aug 12, 2019, 6:36 PM

If you need to use the ALIX that is what I would do. At least you can have a current build on there that will be relatively secure.

hmm can you please look at this,,upon setting this modem AT^SETPORT="FF;16,12,10" suddenly I have this in my log:

ugen1.2: <HUAWEIMOBILE> at usbus1
u3g0: <NCM Network Control Model> on usbus1
u3g0: Found 2 ports.

previously I dont have this log when I set this AT^SETPORT="FF;10,12,16" on my modem..But still no ue0 interface![alt text]

on my vm pf 2.4.4 :

stephenw10 · Aug 12, 2019, 8:07 PM

You probably still need the newer cdce driver.

Steve

@stephenw10
I compare 2.3.5 dev.d/usb.conf from 2.4.4 , my modem intsubclass and intproto is included on 2.4.4 usb conf and missing on 2.3.5 ..can I add this on my 2.3.5 usbconf??

nomatch 32 {
	match "bus" "uhub[0-9]+";
	match "mode" "host";
	match "vendor" "0x12d1";

As a test I can't see why not. I've never tried that myself though...

it didn’t work..I think there’s no ncm kernel module for 0x12d1 Sub=03 Prot=16..

Is there any possibility I can recompile and patch this cdc driver?

stephenw10 · Aug 13, 2019, 10:59 AM

You can try it in a FreeBSD 10.3 box. I have done so with other drivers and loaded them as kernel modules.

I've never seen it done with a USB device though.

If you dont mind can you guide me , I already made an svn checkout on 10.3 , no idea how to apply the patch,and if I compile it succcessfully , I can donate a little some beers..
