[Solved] Huawei Modem E3372h-607 Connect With NCM Error /dev/cdc-wdm0 missing

permanisudrajat · December 10, 2018, 3:16pm

Can Anyone help me?
I want to use Huawei E3372 as WWAN for my openwrt router archer c7, with usb hub, one for extroot and one for huawei modem, but when I'm using the ncm mode, it's not listed in ls -l /dev/cdc* , but it's detected in log,

here is the log

Please help me

Which OpenWrt version do you use, snapshot or 18.06 or...?

Have you already tried https://openwrt.org/docs/guide-user/network/wan/wwan/ethernetoverusb_ncm#troubleshooting ?

permanisudrajat · December 11, 2018, 3:11am

snapshot...
I already try it too...
I install triple of them, rdnis, ncm, qmi, but none of them work,
the /dev/cdc-wdm0 missing, the /dev/ttyUSB missing to...

yesterday I modifed the usb-mode.json, add the following :

"55534243123456780000000000000a11062000000000000100000000000000" # in the message
                "12d1:14dc": {
                        "*": {
                                "t_vendor": 4817,
                                "t_product": [ 5339 ],
                                "mode": "HuaweiNew",
                                "msg": [  ]
                        }
                },

I add that, reboot, when use usbmode -l it's detected like this

Found device: 12d1:14dc (Manufacturer: "HUAWEI_MOBILE", Product: "HUAWEI_MOBILE", Serial: ""

but when use usbmode -s it's not working

please advice me...

I am not sure I can help, but I got almost the same set up without usb hub and it is working fine. I plug my huawei usb dongle to my archer c7 v2 directly.
I am using openWRT 18.06.01 and installed following extra packages:

kmod-usb-net-huawei-cdc-ncm
kmod-usb-serial-option
kmod-usb-net-rndis
usb-modeswitch.

Maybe you want to try your setup without hub first and check out if it works.

permanisudrajat · December 12, 2018, 11:47am

@zkzkzk2015 your device is same as mine?

I already that actually, but with usb hub...

okay I will try it out without usb hub...

EDITED:

I already try it bro, but it's same, not worked...

this its the log:

This is hilink. If you want serial port then reflash modem with proper firmware.

Hilink is like router on usb - only network card is available.

how to do that (reflash modem) ?

You have a choice. Your hilink stick has router capabilites, that means you got double NAT.
Double NAT is usually okay but sometimes (playing games etc) it is trouble.
One solution is described here:
Poor Man's Bridge Mode

I am using it and everything is working fine.
Basically you turn off your dhcp, NAT, firewall and only use DMZ on your usb-modem/router. So most of the grunt work is done by your router behind your usb-dongle.
Configuration of your stick is done via web-interface. Maybe you have to flash your usb-modem/router to get all of the above mentioned features.

I hope that helps.
