Huawei E3372h LTE dongle and NCM/CDC mode

trumee

Hello,

I have a Huawei E3372h dongle which works in FreeBSD 11.2 with NDIS driver. It shows the following,

Jul 22 10:34:28 nas kernel: u3g0: <HUAWEIMOBILE HUAWEIMOBILE, class 0/0, rev 2.10/1.02, addr 9> on usbus0
Jul 22 10:34:28 nas kernel: u3g0: Found 2 ports.
Jul 22 10:34:28 nas kernel: cdce0 numa-domain 0 on uhub1
Jul 22 10:34:28 nas kernel: cdce0: <NCM Network Control Model> on usbus0
Jul 22 10:34:28 nas kernel: cdce0: faking MAC address
Jul 22 10:34:28 nas kernel: ue0: <USB Ethernet> on cdce0
Jul 22 10:34:28 nas kernel: ue0: Ethernet address: 1c:1f:f2:23:dc:00

and it internet can be setup using

echo 'AT ^ NDISDUP = 1,1, "internet"' > /dev/cuaU0.1

On the other pfSense (2.4.3) doesnt show the NCM interface,

ugen0.6: <HUAWEIMOBILE HUAWEIMOBILE> at usbus0
u3g0 on uhub0
u3g0: <HUAWEIMOBILE HUAWEIMOBILE, class 0/0, rev 2.10/1.02, addr 5> on usbus0
u3g0: Found 2 ports.

How can i setup/use NCM in pfSense?

I tried the dongle in pfSense 2.4.4 snapshot (running in virtualbox VM) and it worked. I passed the APN via the shell. Is there any place in the GUI I can specify the APN?

Here is workaround until a GUI option is available,

$cat /usr/local/bin/e3372.sh 
#/bin/sh
echo 'AT^NDISDUP=1,1,"internet"' > /dev/cuaU0.1

$chmod +x /usr/local/bin/e3372.sh

$mkdir /usr/local/etc/devd
$cat /usr/local/devd/e3372h.conf 
#12d1:1506
attach 20 {
        match "vendor" "0x12d1";
        match "product" "0x1506";
        action "/usr/local/bin/e3372.sh";
};

This may not survive upgrades though. So an alternative way would be better.

Just did a fresh install of 2.4.4 release.
Connected the modem and could select the new device for WAN.
I have the similar dmesg output you had with FreeBSD.

Tried the echo command directly but never got an IP.

Also tried with the 2 files you recommend.
/usr/local/bin/e3372.sh
/usr/local/etc/devd/e3372h.conf
But your code is unclear, is it with or without the /etc/ ??

Can I debug something?

corrected code:

$cat /usr/local/bin/e3372.sh 
#/bin/sh
echo 'AT^NDISDUP=1,1,"your APN here"' > /dev/cuaU0.1

$chmod +x /usr/local/bin/e3372.sh

$cat /usr/local/etc/devd/e3372h.conf
#12d1:1506
attach 20 {
        match "vendor" "0x12d1";
        match "product" "0x1506";
        action "/usr/local/bin/e3372.sh";
};

Modem should be running 21.x stick firmware, switching to a proper composition prior to use should not harm:

AT^SETPORT="FF;10,12,16"

Depending on the firmware version used the command above could be not available. If switching to PID:1506 is required that could be achieved by using usb_modeswitch, not tested with the above mentioned scripts though.
