huawei e8372h-153 switching but not recognized as modem

Post by roeeklinger60 » Wed Oct 16, 2019 10:32 am

Hey guys,

I have recently bought a huawei e8372h-153, I followed this guide: https://gist.github.com/guseppiguliano/ ... 1439a03790

and everything worked just fined, when I unplugged and re plugged dmesg | fail -f gave something like "GSM modem connected ttyUSB..."

However, when I restarted my PC back to windows and then back to Ubuntu, the device is recognized as "USB mass storage" in dmgesg, but as a modem in lsusb (it successfully changes from 12d1:1f01 to 12d1:14dc in lsusb). No matter how many times I re plug it it says 12d1:1f01 in lsusb but 12d1:14dc and wvdial is unable to recognize it as a modem.

I have tried uninstalling and reinstalling usb-modeswitch and repeating the guide but dmesg still shows it as a USB device, lsusb as 12d1:14dc and wvdial doesn't recognize it.

Any ideas ?

I am running on a Lenovo usung Ubuntu 18.04.

Thanks !

Huawei E8372h is not a dial-up modem, it is a router with a wifi access point for up to 10 clients.
You can tether over usb to the LAN of this router where you get an ethernet-over-usb connection.

Thanks for the reply !

I actually didn't know that. How come I got a GSM modem from dmesg if it's not a modem ?

BTW which 4G Huawei modem do you recommend ? I am trying to set up a 4G proxy server with WVdial +Squid

4G is LTE Category 3 at minimum and dial-up modems can not fully utilize those speeds so most such modems do only have an ethernet-over-usb function.
Huawei E392, E397, E398 has both dial-up modem function and direct ethernet function, but they are old so probably difficult to find.

dial-up is so yesterday, squid works equally well on an ethernet-over-usb connection so why do you want dial-up?

I will actually look into that. Creating a 4G proxy as not an easy task and to be honest I don't really know what I am doing yet. I saw a guide that this is with WVdial so I wanted to follow that guide. But TBH I am pretty sure there are other ways to do this.
Thanks !

OK so I replaced the current model for a e3372. I reinstall usb-modeswitch but I still get the same problem.l

lsusb shows :

Code: Select all

Bus 003 Device 015: ID 12d1:14dc Huawei Technologies Co., Ltd.
but dmesg shows:

Code: Select all

[  783.810761] usb 3-1: Manufacturer: HUAWEI_MOBILE

[  784.860099] sd 6:0:0:0: [sdb] Attached SCSI removable disk
WVdialconf also detects no modem.

Is the device configured or a modem now or not ? why don't I see a GSM modem message in dmesg as before ?

Thanks a lot.

E3372 is an E8372 without wifi but as I said most 4G modems do only have the ethernet-over-usb function due to 4G higher speed than dial-up can cope with. 25 Mbit/s or there around is the limit for ppp diasl-up, that is not a 4G speed.

If you are using the latest usb_modeswitch (2.52) and you are lucky then it might work to switch this modem into an old dumb slow ppp dial-up modem by enabling HuaweiAltModeGlobal in /etc/usb_modeswitch.conf

The Huawei modems E3272 and E3372 do not provide a PPP port anymore in the alternative mode, only a serial DIAG port and an NCM interface (optimized Ethernet flavour).
It's likely that newer ones follow that path.

Have you got your E3372 to work, and if so how ?

I ask because I seem to have run into the same problem.
